Plan for increasing available tags

This plan is finished for the beelzebufo release. Yay!

Increasing the number of available tags would be easy, except that tags 1000+ are used for automatically allocated one-time-use tags.

• Move one-time-use tags to a separate memory buffer (done)
• Make game store the highest available tag, defaulting to 999
• Update Plot:set tag and plot:check tag to handle tag numbers above the available limit differently, manipulating one-time-tags (done)
• Make new plotscripting commands to get/set one time use tags without using set tag or check tag (done)
• Add a bitset to enable tags higher than 999 (done)
• Increase the number of available NPC onetime use tags (done)
  • This will require changes to how onetime use tags are tracked.
  • gen(106-170) are bits that indicate whether or not a onetime tag is being used by an npc
  • would it be easier to recalculate that information when custom loads a game by checking each NPC record? Would that be too slow? (yes it was and no it wasn't)
  • would it be easier to continue tracking which bits are used in a persistant cache, and just change how/where it is stored? (bad idea)
    • Maybe a new lump?

Note 1

Game authors who already manipulate one-time-tags with "set tag(1000+n, value)" and "check tag(1000+n)" will not need to re-write their scripts unless they choose to increase the available tags in their game
