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.
Two classes base::Observable<Event> and base::Subscriber were added.
base::Observable<Event> can notify about Event-s, while any
base::Subscriber can subscribe and then async receive them.
Now the background of boxes is separated to another widget.
This will allow to use a special layer widget (like settings)
together with the usual layers-boxes upon it, moving the special
widget behind the dark background when a usual layer-box is shown.
MetaLang, codegen_style and codegen_numbers utilities are now
built by GYP targets, rules added for codegen_style and actions
added for codegen_numbers and MetaLang.
WinXP supported without Windows 7.1A SDK, but with explicitly
setting MinimumRequiredVersion=5.01. It works (and that is strange).
If you attempt to use MSBuild instead of Ninja you should add
the latest Windows SDK include paths to include_dirs, because v140_xp
toolset implies the Windows 7.1A SDK (and is ignored by Ninja).
It already builds in Debug, using rules for Qt MOC and RCC.
Need to start use rules for styles/langs/numbers, test on WinXP.
Need to support Release and Deploy configurations.
