Now group of Ui::Radiobutton instances share Ui::RadiobuttonGroup.
All value management is done through the group instance, not through
separate radio buttons. Also a template for groups over enums added.
Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
Added LocalStorageBox for watching info and clearing local storage.
Local passcode and cloud password state display and editing done.
Temporary download location clearing link added.
Crash fixed in local storage clear + app close, now waiting for the
clearing thread to quit. Some design improvements and testing.
Left: auto update, privacy and security, local storage box +
some minor things, like design fixes, codes like loadlang and
clearing of the local storage (box) and temp download folder.
