More Lua API fixes

* Removed `vars.model_orig`
* `requirex()` in bridge.lua now maintains a separate module cache for each
  userscript instead of using the same cache for all userscripts
* `vars.lua_deleted` and `vars.lua_edited` are now erased right before running
  the input modifiers instead of right before each time the generation modifiers
  are run
