Add command 'findsymbol'

[dan-t]

Hi Bit,

I've added the command 'findsymbol', to be able find the modules where a given symbol is defined.

Greetings,

Interesting. Could you please explain a bit more what this does, maybe with an example? And the difference between the "info" command? Thanks!

The 'info' command shows the type information of a given symbol and in
which module the symbol is defined. The basis for this command are the
already imported moduls.

The 'findsymbol' command should be the basis for extending the import
list. The idea is, that 'findsymbol' finds all occurences of the given
symbol, if it's defined in multiple modules, than the user can choose
which one the wants and than the import list gets extended, if necessary.

Until now I didn't have put that much time into the whole thing, but I
have started a simple command line program which should be extending
the import list.

Would you have something against a 'hdevtools import' command:
hdevtools import 'Control.Applicative' '<$>' ?

From a user perspective it would be easier if he just needs to install
'hdevtools' and 'vim-hdevtools' to get the whole thing working.

Hi Bit,

I have done some further changes which I try to summarize.

The first few commits are about better error handling for
the 'findsymbol' command and about catching GHC exceptions
when reading module informations.

The bigger change is about allowing the 'findsymbol' command
to take any number of source files.

This is the basis to be able to extend the import list by
modules of the current project.

Daniel
