Fix vram corruption when using the cheat panel in vertical grid mode

Browse Source 
The graphics of an animated nds icon are now not all uploaded to vram at the same time.
There are now 1024 bytes available for each icon (previously 4096).
Double buffering is used to upload the new icon frame every time it changes.
