Lack of configuration options

[poVoq]

There are quite a few features that are currently turned off to make usage on small screens (Nexus5) possible or to improve performance a bit.

This should be improved by allowing to configure these depending on the user preference.

Examples are:

• send_chat_state_notifications
  • Docu: https://conversejs.org/docs/html/configuration.html#send-chat-state-notifications
• muc_fetch_members
  • Docu: https://conversejs.org/docs/html/configuration.html#muc-fetch-members
  • The member tags are also removed in my mobilefixes.css
• allow_muc_invitations
  • https://conversejs.org/docs/html/configuration.html#allow-muc-invitations
  • Sits on top of MUC member list and is only usable on larger screen resolutions.
• roster_groups
  • Docu: https://conversejs.org/docs/html/configuration.html#roster-groups
  • This is also not supported by some XMPP servers and there is no way to edit them in ConverseJS for now.

And there are also a few other smaller settings that I disabled to make usage a bit easier, but that could probably be user-configurable in an advanced settings menu.

For the PineTab and convergent desktop use, it would probably be good if there was an option to switch to regular fullscreen view-mode instead of the mobile one that is currently used.
