Key state is not updated when pressing keys

[anhcraft]

A few keys currently do not update the state. This is caused because Tensai relies on Minecraft's internal key-handler. The handler prioritizes certain keys first and only fires the rest if they are not functional.
This includes a lot of keys such as:

• Ctrl
• Alt
• Shift
• W, A, S, D
• All mouse buttons
• etc

A patch must be implemented, however there is a few considerations:

• Whether we should allow all keys (including ones used by Minecraft internally)
• Whether we should notice or throw exception at forbidden / unsafe keys
• Whether we should prioritize Tensai key-handling over Minecraft's
