Now everything that uses Profiles from cache will also use it's
mutex to lock access. This brings more stability improvements :).
Also fixed profile update in database.
Qt5 interface is now translated (kinda).
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.
