openbor Tools

openborscript.c:
Fix aiflag and think for changeentityproperty os NULL() is now actually supported.
Add jumpheight as an entity property (set and change).
openbor.c:
Forgot to clear loading script, now it's fixed.
screen32.c:
Fix putscreenx8p32 color key bug.

Allow selecting the OpenGL filtering method (simple or bilinear) in
fullscreen. This was supposed to be allowed when I separated the video
settings for windowed and fullscreen in the save data, but I overlooked it
then.

Silence debug spew to stderr when processing joystick input. I added it a
long time ago for debugging purposes and apparently forgot to disable it. It
went unnoticed until now because the stderr stream is only visible when
running OpenBOR from a terminal in Linux or Darwin.

Rewrote the Scanline 2x and Scanline TV 2x scaling filters to fix conflicts
with the GPL.

Fix crashes in Scale2x MMX implementation.

Fix special3(aka jumpspecial) dive bug.
Fix difficulty menu scroll bar (more than 10 modes are supported now).

Cleaned the Scale2x rewrite up a bit and changed the MMX assembly code to not
use the ebx register. Hopefully this will fix the compile error in Darwin.

Complete rewrite of Simple 2x scaling filter to remove more GPL-licensed code
from the engine. The implementation ended up being very similar, even though
I didn't look at the original code until after finishing my own
implementation.

Enable remap and blend for 8 bit transform (transform.c).
Minor debug message change(openbor.c).

Fix some debug messages.
Fix fill color and remap conflict under 8bit mode (3716).
