- Get rid of some "misleading-indentation" warnings in gcc6
- Fix some compile warnings in aes which got handled as errors by some c++11 compilers.

- Resetting Randomizer with 0 or no longer breaks it (will be set to 1). Same for other numbers for which it wasn't defined.
- Randomizer now returns range 0..randMax as documented and no longer 1..randMax as it did before. randMax got reduced by 1.
- Using now same random numbers as std::minstd_rand0. Not sure if the others were wrong, but documentation mentioned they are for mixed linear congruential generator from L'Ecuyer and as far as I can see we don't use that (that one mixes 2 calculations). We seem to use just a linear congruential generator. (I'm no expert on all this, just what it looks like from net articles).

Probably something which will happen now a lot, would be nice if someone would update the ogre loader.

- Minor improvements in COGLCoreTexture.

COpenGLDriver doesn't seem to need COpenGLCacheHandler or COpenGLTexture as friends. So removed those.
If one of them is needed again please write 'friend class COpenGLCacheHandler' instead of 'friend COpenGLCacheHandler' as 
older gcc compilers (4.4.7) won't accept it otherwise.
Thanks @umen for reporting.

 bool IVideoDriver::setRenderTarget(IRenderTarget* target, ...);
 to:
 bool IVideoDriver::setRenderTargetEx(IRenderTarget* target, ...);
- Replaced some deprecated methods in tests.

- Improved D24S8 color format handling in OpenGL.
- Fixed issue with wrong size for OpenGL RT when FBO isn't available. Thx CuteAlien for report that.

Also added a function to access the original name as well as the converted name for directories.
Can't fix the interface completely unfortunately without breaking it :-/
Not yet fixed is the conversion to lower-characters - that will be one of the next tasks (had to clean up other stuff before I could approach that).
Also _IRR_WCHAR_FILESYSTEM currently not compiling, but been like that a few versions already.

Needed a little more work to disable a warning once in a way such that it doesn't produce other warnings on other compilers.

I had to add a few forward declarations in core::string because I didn't want to add another source-file for this now. If anyone decides to create a irrString.cpp those can be removed again by making multibyteToWString extern instead of static (in VS it would already be possible to avoid them, but gcc does more exact checks for friend linkage specifiers).

Flip around default parameters in beginScene and setRenderTarget in a way that causes less deprecated warnings, but still does the same in general. That avoids some troubles with function resolution when only first 2 parameters got set (otherwise needed explicit casts to u16).
Use new image->getData in example to avoid warnings.

- Removed *.nib dependencies from OSX project (menu is created programmatically).
- Added missing _IRR_OVERRIDE_ for some methods.
- Renamed MacOSX to OSX directories.
