Less alerts and rlv spam, more attempting to sit if possible

[nooperation]

• AutoSit no longer attempts to sit on objects that are not in the current region to prevent alert spam
• AutoSit checks RLV unsit permissions before attempting to unsit to prevent RLV spam
• AutoSit will now always stand up and sit on the correct object if it becomes available

looks good, thanks.
