Adding Lua 5.2 support to Windows and Android build systems.

Added switch to VS 2010 and Android build to switch between Lua 5.2 and Lua 5.1 interpreter.

When building with 5.2, luaext is not included in the build because since migration to 5.2 of this module is not trivial. Also some methods in MOAILuaRuntime are disabled for the same reason.

Since luasocket is not built with Lua 5.2, ZeroBraneStudio debugger won't be able to connect to the MOAI host.
