openbor Tools

1. Dynamic allocate script buffer.
2. Commands like jumpframe now accept "this" as the frame index parameter, which means current frame. For example: jumpframe this 3 2 0
3. Add several commands in levels.txt and models.txt to change default values for those HD mods. Still working on.
4. Minor change in function check_attack_chance, keep a reminder here.

Change hitpause logic. Now use pausetime as a timer and remove lastanimpos flag. This should take care of possibly multiple hits within a single frame.

Fix occasional crash caused by common_idle_anim. Should always be careful when using global variable self.

Make stop before player turns, for keyboard users can press left and right at the same time and will leave the player sliding while turning.

- Skip unsupported aiattack command arguments to be more tolerable for older mods.
- New script function strwidth for calculating display length of a string.
strlen("string", font_as_integer)
- Edit strlength function, simplified the code, and will now show error instead of warning if the parameter is not string.

Add combostep and combotime to getentityproperty and changeentityproperty.

aiattack command now available.
aiattack normal (default).
aiattack noattack (do not attack even if you give attack animations)
aiattack always (more aggressive than normal, like old version)

followcond 2 now checks hostile instead of candamage.

Add maxfallspeed, maxtossspeed and gravity to scripted level properties. Also change getlevelproperty and changelevelproperty to use their own mapstring function.

Add current_branch to openborvariant to get the branch name current level belongs to.
Fix in game player select icon palette.

Add an extra parameter to function check_costmove to distinguish situations like jump.
This is a temporary fix, will clean up the logic later.
