Partially check update_frame animation change after execute_animation_script, since most script users should intend to skip current frame immediately.

Change animation script logic so weapon model can have their own animation script without overriding the original one.

Fix update frame wrong frame pointer bug (animation changed in a script or weaponframe but frame number stays, so function is actually using an unexpected memory address).
There's a side effect from this fix that jumpframe or sound in previous animation will still be played, so I'll wait feedbacks from script users.

Change time values back to u32, because I noticed several bugs that were hard to trace.
Now check stalltime carefully when there's a minus instead.

Add a new value for modelflag so scripts can also be ignored.
Remove notinair check for cancel, since user can combine landframe and cancel window frames.

Check nomove in common_move and return, so custom velocity can be used.
Fix range picking logic, previous logic tend to choose freespecials too much.

Fix entity drawmethod alpha property.

Change check_range macro so it is possible to return true when minrange==maxrange.

Disable ai character attacks if target is rising and doesn't have any bbox.
Change normal ai move destination points a bit.
Unused function assume_safe_distance.

New script function getpixel(handle, x, y, type).
Get a pixel from specific screen or sprite.

type - screen or sprite (or other format if supported in the future)
0 - screen
1 - sprite

x,y - position, for sprite, centerx and centery is not considered. If the point falls out of the dimension, the function returns 0.

handle - screen or sprite handle, must be valid.

return - For 8 bit image, it returns the index. For 16 and 32 bit, it returns the color as an integer.

Don't try to set a new color table if the drawmethod already has one.
Unless the entity is doing dying flash.
