Frostbyte's Improved Inventory

Additions:

• Added a zoom key (c by default)
• Added shears to the list of items that the tool selector can swap to

Bug Fixes:

• Fixed container sorting not working for certain items

Changes:

• Implemented a 2 tick cooldown between tool swapping in an attempt to prevent the held tool from swapping when a block that can be broken instantly has a different block underneath
• Removed the Sort Inventory toggle from the config menu, as unbinding the key (middle mouse by default) works the same way
