4edd4b7cc8 Major refactor. Major improvements. 
All ISR/IRQ stuff moved into its own header and source.

Comments added on all major parts.

Some optimisations in important functions.

All ASM removed for ISR and IRQ, instead using new GCC directives.

f5dc9b961b Collate ASM files 
All ASM now uses Intel syntax.
isr.s and gdt.s are now collated into the main file.
It's bulky, but ¯\_(ツ)_/¯
UNTESTED, cause i'm thick.
