Update 0.2.1

[h2]Changelog[/h2]
Improvements
- Shelves can now hold more items, there will always be at least two rows of items, even for smaller ones.
- USD banknotes and coins now have correct denominations corresponding to reality.
- All coins of all currencies now have the correct texture.
- Increased the resolution of banknote textures, making them easier to distinguish.
- The highest denomination banknote is no longer useless, as customers can now pay with an even higher-value banknote.
- At the end of the day, all items held in your hands are now removed.
- Throwing items into the trash now discards all items in hand, not just one.
- When placing an item from your hands onto a shelf, the last picked-up item is placed first, as expected, allowing you to easily return the last grabbed item if you picked up the wrong one by mistake.
- Added an "Unstuck" button to the menu in case your character gets stuck behind a wall.
- Added support for displays with resolutions lower and higher than Full HD. The interface now scales correctly.
Fixes
- The coffee machine now works correctly in multiplayer, not just for the server host.
- Fixed a bug where items could sometimes remain on the floor in a single spot and couldn't be picked up.
