Add a "ship" and let the player move around. This includes some tile / palette data in a separate file and some code for DMA'ing that data into VRAM. This is used to render a "ship" (white circle) that the player can move around with the D-Pad. Added a whole bunch of named registers (& documentation for them) to registers.asm.
