Keyboard keybinds and Reshade intergation ConCommands

[MCPO-Spartan-117]

Feature request

Having ConCommands for the Nested keybinds would allow them to be used for embedded cases(or remotely for what ever reason),

Reshade ConCommands would be nice as well, i personally use it for color management(I know about the warning but i don't really have any other option atm especially in embedded) but can't swap for another Shader or Texture, or just disable the used Shader.
