Allow loading PNG/JPEG/MS DIB bitmaps from Lua, and cleanup.
Use VirtualAlloc rather than VirtualProtect on Windows to change page protection, as the latter can cause severe performance issues with some antivirus software. Added noexcept to lots of hash- and bitmap-related things, and added a little more error checking. Yes, I realise it will abort if an allocation fails while printing a log message, but if you get to that point, you're probably screwed already.
