Remove OS titlebar on Android

[birbilis]

Version: 0.6.0

Android version shows OS titlebar which is annoying on mobiles with not much screenspace available to waste

Can get rid of it:

Not sure what the behaviour is in that case on ChromeOS or other OS that can run Android apps. Probably would show the app in fullscreen instead of windowed if it is configured to not show the titelbar (value of the theme key set to No TitleBar at Project > Options > Version Info in Delphi)

note that on iOS one has to set BorderStyle = None to their forms

doesn't seem to work even though using NoTitleBar theme on Android (seems it has a NoTitleBar-FullScreen variation - at least when searching with GrepWin for TitleBar in the code - that could be wrong)
