58986: Set Home To Default Attributes

Used by the routines at Controls_CheckRight and Controls_CheckLeft.
Home_DefaultAttributes	58986	LD DE,22562	DE=22562 (attribute buffer location).
	58989	LD HL,59043	HL=HomeAttributes.
The home block is 4x4 (4 rows of 4 bytes) but not all of it cycles attributes. Only 3x4 is used here.
	58992	LD B,4	Set a counter in B for 4 rows.
Home_DefaultAttributes_Loop	58994	PUSH BC	Stash the row counter on the stack.
	58995	LD BC,3	Copy 0003 bytes from the attribute buffer to HomeAttributes.
	58998	LDIR
One full row is 32 bytes, so this is 3 bytes less than one row. Hence this moves down one row, but back to the start of the line.
	59000	EX DE,HL	Add 0029 to the attribute buffer position.
	59001	LD BC,29
	59004	ADD HL,BC
	59005	EX DE,HL
	59006	POP BC	Restore the row counter from the stack.
	59007	DJNZ Home_DefaultAttributes_Loop	Decrease the row counter by one and loop back to Home_DefaultAttributes_Loop until all the rows have been updated.
	59009	RET	Return.
