Attempt to solve Issue 935: Script Chat Show The Owner?
Update rlva (mainly in llviewermessage.cpp)
Tiny changes to have llviewermessage.cpp line up better with upstream
Feature Request: Ability to automatically accept all inventory offers

Replaces the exposed setting in popups preferences
However, for users wanting the old behavior of just landmarks, notecards, and textures being automatically accepted, the original setting(AutoAcceptNewInventory) stays as is, it can be turned on and off in debug
Allow autoaccept to work when in busy mode by handling it first
Don't open inventory offers if busy, busy means busy.
Fix up some logic with always allow fly

The fly button on the toolbar would enable itself despite RLVa restrictions
 - This was because always fly was checked after gAgent.canFly(), despite the fact that gAgent.canFly() itself checks always fly setting at the correct time.

When teleporting to a region that blocks flying, the agent would start flying due to a strange check inherited from upstream.. My opinion is, they want gods to fly, but that's kinda strange too, so I've changed it to set flying false in this case.
