Add more hotkey outputs including DPad direction keys and LS/RS directions

[jack2game]

Currently the hotkeys section only allows output of none directional keys.

It would be great if directional keys can be set as output too.

As of version 0.7.10 we now have hotkeys for DPad directions

Would love to be able to add hotkeys for the right stick
