"skill" cvar is bounded both in the engine and server #4009

the skill cvar currently is locked between 1 and 3 on both the server and the engine

I propose that the extraneous engine sided bound is removed to allow for more game difficulties to be added by modders (such as the mod I am currently making which requires a 4th difficulty setting)

WORKAROUNDS:
adding another cvar then setting the skill globals to a value based on it fixes this issue (and is also required since you can't add more difficulties in the menu without a custom gameUI.dll [Valve pls fix])
