0.6-pre1

The reason this update exists is because it fixes a lot of bugs and contains a lot of improvements.
I still have more features planned for version 0.6, so this serves as a sort of in-between version.

• With the non-general tool block picking, more blocks can now be picked

• Sneaking and throwing the general tool is now an alternative way to open the menu
• UI changes and fixes
• You can now select which alternating axises checkered uses
• You can now disable updating the brush block every time the brush is used, which causes there to be less latency when using it

• Added command functionality for command block chain and structure corner
• Added more error messages (yay!)
• Added an option to show a progress bar
• Added an option for performance warnings
