HighGravBlocks

Adds special high gravity by touching Air Fool X-ray BTS 03, and takes it away when you touch Air Fool X-ray BTS 04.
Space Used: Some stuff in 7E (RAM). Uses debug code slot at $05D5 and writes the code at $F640.

Also, equipping Gravity Suit negates the effects of the high gravity. You can change some of the code to suit your hack;
wherever I put $1C, put your hack's normal gravity in air, and wherever I put $3C, put whatever amount of gravity you want (this is the gravity when HighGrav is on).

NOTE: Only affects gravity in air, not water or lava.
