Editing May 9 2023 build

This build is mainly a Mac update build, I made a number of fixes and reorganizations to it.

For all platforms, Skyscraper now reports the OS version on startup, and on Mac and Linux, the SBS banner is now properly displayed (it wasn't showing before), this was made possible by a wxYield() call before the startup pause. Also, source builds are now about twice as fast, since Skyscraper now uses precompiled headers to speed up the Ogre header processing.

'''For Mac systems:'''
#unpacking the DMG file is now faster due to me reverting to the default compression method.
#Skyscraper now works properly on MacOS 10.13 and 10.14, in case anyone is using those versions. 10.13 is the earliest the current build compilation supports.
#certain keys such as ";" (start new engine) and "[ and ]" (change zoom/FOV) now work properly on Mac
#fixes were made to the source builds on Mac, CMake now automatically copies the binary into the Bundle folder, and a script I made copies the libraries into the Frameworks folder, so now you just have to "make" and run, making builds and testing a lot easier.
#dylib libaries have been moved into the Frameworks folder instead of the MacOS/Libs folder, to follow a more Apple-like method.

'''Changelog:'''
#Use precompiled headers to speed up build
#Report OS version on startup
#Revert ContentScaleFactor value to 1.0 on MacOS versions earlier than 10.15
#Don't process "stuck key" fix on Mac systems
#Configure Skyscraper's binary to use the Bundle framework
#Automatically copy OgreBullet and SBS into bundle on Mac
#Add a wxYield() call before the sleep() call, to print the SBS banner properly on Mac and Linux
#Report on initialization complete
#Revert dmg compression to default on Mac builds (was previously bzip)
