Improve overall ff8_Demastered code

[julianxhokaxhiu]

• Add Debug stacktraces in the log file when crashing
• Improve debugging code for an easier debug output
• Log files will always start clean on each game startup
• Redistributable files will now be generated in .dist folder
• Build artifacts will now be generated in .build folder
• Upated .gitignore to ignore .NET stuff ( rules inherited from default Github gitignore repo ) + custom entries regarding build/distribution
• Add support for OpenGL compressed textures ( allowing compressed DDS/BCn to load fine )
• Add support for PNG 24/32 bit ( and use as fallback if no DDS file is found )
• Add support for Mipmaps in both Compressed an Uncompressed texture files
• Add Third party libraries section in the README.md
• FF8 Demastered DLL is now statically build ( no other dependencies required or 3rd party DLLs )
• Code is mostly warning free ( very few minor left, all the rest is gone )
• Solution has been tweaked to provide a single target ( Debug ) with x86 ( for the DLL ) and AnyCPU ( for .NET ) in order to ease the first build after clone
• Third party dependencies are now located in a folder named vendor, with /lib and /include folders used by default by the project

What is left:

• Hook every inherited GL function where the PNG external textures are loaded, in order to override that and allow us to load DDS textures too ( glCompressedTexImage2D is required for that )

Thank you!
