Keyboard binding fixed + a couple of minor fixes

Hi everyone,

FIrst, I'm sorry about that keyboard binding thing. I have no idea how it happened, I probably messed it up in one of my last updates.

Fixes

• Keyboard binding works now

• You can't leave the options menu when you are in the pausing menu, you need to close it first

• Typo in french on the "Gamepad..."button.

Thanks everyone for your feedback!

Yann
