- Moved destination tag off of linedef tag and into args.
- Bot controller values can be changed mid-level with ACS. (Linedefs using type 2004 will still be activated on level load.)
- Add flag to make bots fastfall
Previously, there was a permanent exception for Eggrobo (the default bot skin).
Now that exception is generalised for the specific skin the bot is being assigned, which we assume is intentful and correct.
In addition, the randomclass PR_BOTS now controls K_RetireBots as well, matching the other two random calls done for bot skins.
I'm not sure exactly where the bot code leaks, other than knowing its the prediction for sure (because the prediction is the only memory bots ever allocate), but srb2::finally is cool and lets me not care :)
