Use dynamic alloc for many level and model properties.
Add wall and hole to script level property.

Remove the __EndMMX() function. In the one place where it was used, it has
been replaced with a single line of inline assembly that does the same thing.

Fix link error on Windows caused by different function name mangling on
Windows and Linux. This should fix the reported link error on Darwin as well,
although I don't have a working Darwin toolchain at the moment.

Minor change: don't use transform for sprites that only use centerx and centery drawmethod properties.

Avoid clobbering the ebx register in GetMMX since Darwin uses it as the PIC
register.

Rewrote the bilinear scaling filter. Like the previous version, this one has
both a C version and an MMX version. Unlike the previous version, the
copyright is owned by OpenBOR Team and it's not licensed under the GPL.

Removed the "Bilinear Plus" and "Motion Blur" filters. Both were
GPL-encumbered and rather useless as filters, and a poll of users didn't
show that anyone actually uses either one:

Add quake to level property.

Merge alpha 7 with alpha 6 (engine will check if channels are set).
Add tintmode and tintcolor to drawmethod, if tintmode is set, it tints the sprite with specific tintcolor and blend mode(defined by tintmode).

- Add alpha 7 (individual rgb channels) and corresponding drawmethod properties (channelr, channelg, channelb) and script changes.
- Twist drawmethod command to break it down to smaller ones instead of single long argument list.
- Edit macros in pixelformat.c to swap r and b with each other (r is actually b and vise versa).
