Auto Layout Improvements

[MosheBenZacharia]

Adds new functionality:

1. Previously when additional items (new items or variations / fuzzy matches) were being added, they would fill in the first empty space in a layout. Most noticeably when using Inventory Setups with Presets layout this would cause items like potions to pollute the equipment area. There is now a new config option to add variations after the last item.

Before:

After:

2. In addition, there is currently no way to delete/override an existing layout without changing the name of the setup or deleting it from the config. This PR revamps the 'auto layout button' to include new options:

• Set zigzag
• Set zigzag (fresh)
• Set presets
• Set presets (fresh)
• Reset

The 'fresh' options will perform a more invasive auto-layout that will discard the existing layout. The 'reset' option will clear any layout data.

3. Lastly, canonicalizes items in inventory, to prevent noted item placeholders from appearing in the bank.
