Fixed favorites servers - they now correctly added/removed in/from cache,
and also fixed favorite server edition dialog, which now also takes
advantage from server's cache.
Added new toolbar button for updating one server. It works :).
Added new column in servers lists, which shows is server is private or public.
Now we have pooler which will pool connections (like pinging),
so there will be no timeouts due to "we have launched 100000 goroutines".
Reworked all code to use events (see Eventer). Still more work about
this to go.
Maybe more fixes I forgot.
Adding a favorite server now requires created valid profile. It will
not allow to create favorite server without proper profile.
Fixed servers updating database, now they put all fields there.
Added stubs for players info and extended server config things in
database.
Favorites functionality done, except editing favorite server.
Note, that game profile defined for favorite server have
higher priority on normal profile selected in combobox near
"Launch!" button. Later WILL be ignored.
Bunch of fixes is added.
