Moved MembershipListHandler class to separate file.
Removed unused dependency.
Better unread refresh.
No longer disables auto refresh of unreads on failure, but instead delays
the next attempt a bit longer.
Moved HttpkomConnection class to separate file.
Initialize all MembershipListHandlers when loading saved connections, so
we start auto refresh even for non active sessions. Also reset auto
refresh timer when doing a manual membership refresh.
Removed unused code.
Use pagination and fetch the last 100 created texts, instead of only
the last 10. I don't think this solves bug #24, but it makes the function
a bit more useful.
Added default for textMode when displaying texts. Fixes the problem that
the presentation isn't shown without clicking on one of the text mode
buttons.
