Update 1.5.1.48

Camouflages and fixes.

Camouflage selection functionality has been added. Currently it is only available in view mode. Changeable camouflages will be available a bit later: after 10:00 (GMT) camouflages will be available for Big Trophy vehicles, and the option to switch between premium and basic camouflages on all other vehicles will appear gradually.
A bug that caused the game to crash on some devices on the Rheinland map has been fixed.
Postwar German and Japanese tanks are now marked with modern German and Japanese flags.
