This allows us to import the app module without triggering
dependency detection
Also add is_installed() for checking if a dependency is installed and
disable_dependency() in case we dont want to use a dependency
The new Placeholder text inside MessageTextView was causing many
buffer changed events.
- Add a method that lets us know if there is user input
- Add logging
- Move ActionBar into HeaderMenu
- Make Design of ChatControl look cleaner
- Hide the Roster in Groupchats per default
- Add Button to hide/show Roster in Groupchats
- Move Groupchat topic into popover
- Display Avatars on the right side of the ChatControl and status on the
left
- Add a default Avatar for contacts that have none
- The 'configure-event' does not trigger anymore when connected to
the MessageTextView. The reason is unknown.
- Use our own ScrolledWindow Widget instead so we can better control
the dimension of the MessageTextView
