Fixed whitespace, removed unused methods, corrected documentation.

Resolved Conflicts:
	daemon/src/managerimpl.cpp

Whenever we hangup or our peer hangs up a call, an entry is added to the history
(in memory). When the daemon exits, it will save the history
automatically.

It only does it once, when saving it (at exit).

This way we only have one representation of the history in memory
instead of 2, and we don't need a ConfigTree for this, standard streams are
sufficient.

We were inserting elements into the toolbar at invalid positions.
Now the indices have been corrected and an assertion added to make
this sort of error more obvious in the future.

Clients still need to be updated.
