* Updated the options definitions to the new api
* Fixed the wrong base class being used for UndertaleOptions
* Undertale: Added get_filler_item_name to Undertale, changed multiworld.per_slot_randoms to self.random, removed some unused imports in options.py, and fixed rules.py still using state.multiworld instead of world.options, and simplified the set_completion_rules function in rules.py
* Undertale: Fixed it trying to add strings to the finished item pool
* fixed 1000g item not being in the key items pool for Undertale
* Removed ".copy()" for the junk_weights, reformatted the requested lines to have less new lines, and changed "itempool += [self.create_filler()]" to "itempool.append(self.create_filler())"
* Changed the pathing code to use os.path.join, instead of adding strings together, also fixed the savepath command using UndertaleContext instead of self.ctx (Credit to Wackerly for finding the self.ctx issue and fix)
* Undertale: Fixed a debug function in the game not requiring debug to be enabled.
* Undetale: Fixed a logic bug with the location "Letter Quest"
Randomizes the items, and adds a new item to the pool, "Plot" which lets you go further and further in the game the more you have.
