Windows Port

Fixed an error with handling of scanf (for some reason it wouldn't show specifically when calling make from VSCodium's terminal, the default shell showed it fine though)
Now supports the Windows API.

Crash fixes

• Fixed pointers going out of bounds and potentially matching unrelated pointers.
• Fixed being able to select the discard pile when it is empty.

Initial Release

The first functional release of kb-solitaire!
Currently only Linux is supported (officially; you can try it on other machines if you want to lol), but I hope to eventually support Windows as well.
