Capitalism

Medium patch!

- Added a command to reset all rules at once to default state: /capitalism rules reset all 
- Many UI adjustments in configs and the shop
- Updated shop tabs; more organized now with better logic but still experimental.
- Combat shop tab has experimental subcategories: Armor, Melee, Ranged and Utility. Proper version already under work.
- The shop is less crampy now.
- Added a Quick Sell Keybind option in shop's config. Default: Q
- Changed defaults of some pricing rules. 
- Cleaned lots of code and got rid of some errors. It is clean now and should take less space; or at least the same with more features.
- Fixed and heavily adjusted config and rule reading logic.

IMPORTANT!

This update completely overwrites previous manual settings in the config regarding rules an pricing. Just in case use the newly added reset all command; it's only a one time thing but necessary to help servers update unadjusted prices or rules in the future with default settings. Alongside the old version, please get rid of these two if you don't want a mess in your files:
