Some UI related QoL improvements.

For brevity, just going to list a few things assertively.

- I would like to see a collapse/expand all button in the Skills Menu.

- Have the Gem Menu retain it's collapsed/expanded state for specific skills between zones. (Changing zones reverts the skills back to fully expanded state)

- The "copy item" feature on the PoE2 trade site to check items in PoB

- While holding Ctrl to sell items at the vendor, the item stats for the next item you mouse-over do not appear until you release Ctrl. This is inconsistent, but happens regularly. This mostly happens when moving the mouse to a new item, immediately after Ctrl+clicking to sell. This does not happen when using Ctrl+click to move items to stash.

- The ability to change stash tab folder colors.

- The ability to open the Gem Crafting Menus without requiring a respective skill/spirit/support gem.

- While in the Gem Crafting Menu, the ability to craft gems if an applicable uncut gem is found in the player's inventory. Select skill/support -> select from valid gems.

Awesome suggestions! These would really improve QoL across the board.
