Hyperbole 7.0.9: TEST RELEASE - region throws; frame dragging; improved org integration

Many issues were resolved in this test version as documented in the "Changes" file.
Only new features are listed here.

ACE WINDOW PACKAGE INTEGRATION - fast window and buffer switching

- After installing the ace-window package and loading Hyperbole, execute
  (hkey-ace-window-setup "\M-o") to enable the following capabilities:

- Region Throws: The hkey-throw command bound to {M-o t} now throws the
  active (highlighted) region, if any, into the target window's buffer,
  rather than replacing its buffer with the source window buffer.  If
  you don't use region highlighting, i.e. transient-mark-mode, then use
  {C-u M-o t} for the same effect.  The buffer in the target window
  must differ from the one in the source window.  With no region
  active, this command still throws the source buffer to the target
  window.  See "DEMO#Displaying File and Buffer Items and Moving Buffers".

SMART (ACTION AND ASSIST) KEYS

- Modeline Drag Window Resizing: Smart Key window resizing now provides
  live feedback during the drag.

- Bottommost Modeline Frame Moving: After adding a 'drag-with-mode-line'
  frame parameter with a value of t, a drag of any of its bottommost
  modelines with either Smart Mouse Key repositions the frame on screen.
  See "(hyperbole)Moving Frames" for information on how to configure this
  feature.

CUSTOMIZATON

- hproperty:flash-face: Face used when flashing a button; now customizable.

- hproperty:highlight-face: Face used to highlight a line; now customizable.

- inhibit-hsys-org: See ORG MODE section below.

GLOSSARY

- Hlink Definitions: Added Action Button, Elink, Ilink, Glink definitions.

HYCONTROL

- Buffer/Window Swapping: Improved {~} so current buffer remains the same but
  the selected window changes.  Also made frame buffer swapping work anytime
  there are two or more frames regardless of how many windows in each.  See
  "DEMO#Swapping Buffers".

HYROLO

- Hyrolo Add: Fixed new entry addition to add in sorted order and make logic
  operators perform properly, after a bug in level calculation had been
  introduced.

IMPLICIT BUTTONS

- Double Quoting Key Series: Key series delimited by {} may now be in double
  quotes, e.g. "{C-x o}".

- Windows to Posix Paths: Much improved conversion of MSWindows UNC paths to
  existing Posix mount points when running Emacs under Windows Subsystem for
  Linux.  See

- Flashing Implicit Buttons: More types of implicit buttons now flash when
  activated.

- Improved Grep Output Parsing: Recognizes file names with spaces followed by
  the null (^@, ASCII 0) character.

- Texinfo @-Quoted Path Variables: Hyperbole now can resolve paths as
  complicated as this: @file{$@{hyperb:dir@}/DEMO#POSIX and MSWindows Paths}
  in Texinfo files if the Action Key is pressed on the / or after, i.e. after
  the variable name.

KEYS

- Deleted C-c C-r Global Binding: Removed {C-c C-r} key binding for explicit
  button renaming due to conflicts with some major modes

ORG MODE

- Implicit Button Support: Org-mode's local binding of {M-RET} by default
  now activates Hyperbole implicit buttons when within them.

- inhibit-hsys-org: New customization that when set non-nil disables
  all Smart Key support in any Org major or minor mode.

- hsys-org-hbut-activate-p: Added to org-metareturn-hook so local binding
  of {M-RET} in org-mode activates Hyperbole buttons when point is over
  them. (It doesn't run the full set of Action Key actions).

PROGRAMMING

- Auto Imenu Reindexing: If using Emacs imenu package, the Action Key
  will look up in-buffer identifier references with imenu.  If imenu's
  index is rendered invalid due to large changes in a buffer, Hyperbole
  will now automatically rebuild the index to have correct pointers.
  (Does not require use of the imenu-auto-rescan setting.

- hypb:mark-object: Gives Hyperbole-specific strings and symbols
  a hyperbole property that distinguishes them from other objects.

- hypb:object-p: Tests whether has the hyperbole property.  This is useful
  in hpath:relative-to and hpath:absolute-to where any string with a
  hyperbole property is ignored as a potential path.  For example, this
  prevents removal of trailing whitespace from normalized key series.

- hbut:act: Hyperbole button parameter is now optional and defaults to
  the located button, the symbol, 'hbut:current.

- ibtypes tag lookup: Implicit button type names such as ibtypes::grep-msg
  are now properly found in tags tables using their defib names
  (e.g. grep-msg).

- hmouse-drag-p: tests whether absolute Smart Mouse Key depress and
  release positions differ (relative to display/screen coordinates).

- hycontrol-quit: Unified the two Hycontrol mode quit commands into this one.
  hycontrol-abort: Renamed from hycontrol-abort-mode.

- hyperb:autoloads-exist-p
  hyperb:maybe-generate-autoloads
  hyperb:generate-autoloads: Added and called from hyperb:init when
  initializing Hyperbole to generate auto-autoload files when
  running from a non-packaged source download of Hyperbole.
