Remove the now-redundant comments

[Rangi42]

Many lines have comments that are trivial if you know the basics of GBZ80 assembly. Some also appear to have been added before functions and variables had meaningful labels. For example:

• ldh [hMapROMBank], a ; save map ROM bank
• call PrintStatusAilment ; print status condition

	ld a, [wListPointer]
	ld l, a
	ld a, [wListPointer + 1]
	ld h, a ; hl = address of the list

Some will also be redundant once we add more labels and constants. For example, bit 0, a ; was the A button pressed? should be bit BIT_A_BUTTON, a.
