[RAPPS] application-view refactor (#3003)

* [RAPPS] separate application-view from gui.cpp
* [RAPPS] make the code looks more clear
* [RAPPS] fix &  improve tab-order handle
* [RAPPS] now double-click / right-click & install an item will install exactly this app
* [RAPPS] add handling for DWORD timestamp for InstallDate
* [RAPPS] make the code setting column style more clear
* [RAPPS] change the owner of popup-menu
* [RAPPS] now the popup menu (the one when right-click listview) now belongs to application-view
