TomAwezome db32fdb367 Reformatted entire codebase.
Reformatted DolDoc files, adjusted sprites in documentation to reflect naming changes, corrected keybinding labels in AutoComplete window, fixed formatting error in Tips.DD.

Added DVD Boot AHCI prototyping into Kernel, displays detected AHCI configuration and halts mid-boot.

Small modifications to standard font, slight increase to mouse X and Y speed.
