Bananymous c0bc002ac6 Kernel: Move debug printing to its own file

Bananymous 1b9f7aa815 Kernel: Rewrite the whole VESA driver 
We dont support vga text mode currently. I might add it later if needed.

I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
