Changes to N64.

[EGAMatsu]

I added new defines, specifically:

1. ULTRA64, Which is for changing blocks of code for the N64 compiler.
2. TFILTER, Enables texture filtering on the N64.
3. R480i, enabled 480i rendering/640x480.

I also made a define that forces a lower render distance of 20 blocks, enabled by default on the N64, its stored in Constants.h.

Also made it playable by changing the analog stick speed.

Changed it so the C-Pad is now mirroring the D-Pad.

Fixed texture rendering bugs for blocks, at least as far as i can see, I have not tested it extensively yet.

It seems that if you add 0.01f to all of the u1 and v1 variables in Drawer.c, that also avoids texture bleeding issues
