Shop system upgraded (Patreon)

I have upgraded the shop system I had added in the previous releases, the first thing I have changed is having the owned money box separate from the item's description as it did not have sense to have it there.
The position and look of the box will tell the player that it is their owned money right away.

I have also added new categories...
The inventory category is pretty much the same (the flute was just a test item, it will not be sold by the alchemist);
Services will be offered by the Carpenter and the Alchemist, the carpenter will offer basement upgrades whereas the alchemist will sell item creation tools (so far no service was added);
Sell will allow you to sell items for half of their worth, it will be pretty useless for secondary characters but the protagonist will be able to sell items created by him granted that he will pick an item creation feat and also purchases the tools necessary.
