Controls Remapping

First of all I feel that the CTRL+[KEY] buttons (such as the copy and paste configs feature) should be rebound to CMD+[KEY] as this just makes more sense on mac.
Furthermore, I'd like to see a way in which you can generally rebind all the controls:
- For one, the delete key (although you can use X) is not available on all keyboards, I personally feel the X key is uncomfortable to use when using WASD.
- Although not entirely applicable to me, I know a lot of people prefer to control the camera with a different key configuration as it works better for them (be it because they're left handed, or just prefer it that way).
