AI: Finetune ai code after testing on some mods.
Script: Add support for continue statement, needs more test, but at least it works in for loop.

Missing type for fglayer, added.
Make getlayerproperty and changelayerproperty print more accurate error messages.

Don't adjust direction too frequency for wander type ai, or it looks panic. Should be a temporary solution until I rewrite the logic for wander type ai.

Only give default bgspeedratio for background type layer, or strange things happen in some old mod like Night Slasher X.

Make avoid type a bit more aggressive or else they won't attack at all.

Use same logic for pick up item logic.
Although when path is blocked it still looks bad.

Reworked aimove.
Entity now uses a destination point instead of xdir/zdir only. This change should have removed most flickering problems.

Make riseinv accept float argument.

Fixed a crash issue when level has no background.

Script function finditem now returns proper value, previous update missed the return value.

Add aicheckpathblocked to handle default behavior when the path is blocked.
