Context-Sensitive Controls Menu

Very small and simple update here. Took a couple of days away from development for some IRL stuff (boo).

Got back this evening and added in a display of the controls currently available to the player. I'm not too sure how scalable this will be going forwards, but it's definitely a good start.

The groundwork is there for me to switch control schemes too, as some people seem to prefer A/D for strafing left/right but at least this way it is immediately clear what controls do what. I just need to add an options menu to the main menu (and a pause screen, so you can edit while playing)

Tomorrow I'll start some proper work on the camera, as it is currently 12:30am and I am quite tired from travel.

As always, thank you for the support, I really appreciate it!
