v1.0-rc5 - Fix issues with the new input

As mentioned earlier, the previous release broke a few things:

• The rebind screen wouldn't display the "Back" button in some specific resolutions
• If there were a previously saved input, the "Drop from ledge" action wouldn't work

This release fixes these two issues.

Changelog

• Fix displaying the last menu entry in the Rebind Inputs screen
• Reject and revert invalid input configurations
