Minor changes:
1. Remove time checking for gfx_y_offset, otherwise the screen starts 4 pixels lower and immediately jump up by 4 pixels. Can't see why the checking is necessary, but will keep an eye on that if something unusual happens.
2. Use alpha 1 for Game Mode scroller background.

Removed MAX_WEAPONS limit, the constant is still there for backward compatibility.

Temporary fix for select screen summon/spawn y offset.

Restore changes lost since 3528, missing logs later.

Rearrange menus to fit bigger fonts.

Fix script while statement infinite loop bug since 3515.

Fix a label memory leak issue in Parser.c

Reset weapon entity idle or spawn animation when dropped, as if it's newly spawned.

Forgot to handle pathfindstep command in load_cached_model, now added.

Add some comments to ai functions.
