Michel Heily b6e2d55550 Everyday I'm ~~shuffeling~~ refactoring.
Some big refactors:
* improve scheduler performance by using a BinaryHeap
* refactor the scheduler API
* arm7tdmi
	* Change struct arm7tdmi::Core struct layout so frequently accesses fields would benefit from CPU cache
	* Simplify and cleanup cycle counting by implementing a MemoryInterface trait
	* Still not passing many cycle accuracy tests, but I believe it's because I don't have the prefetch buffer yet.
* Timer overflows are now scheduled
	* This fixes #111 and fixes #112
*

Michel Heily 0de8a60006 core: Start working on a scheduler
A more robust cycle aware event scheduling, to easily implement serial-io, dmg audio channels and improve accuracy.
This brings a slight performance hit :/

I also ran dos2unix on some of the files :D
