Setting noclip velocity

[khanghugo]

Hook works great. But then when I try to navigate these tinily huge maps, I bump into teleport all the time.

This has been something on my mind for a while.

My idea for the implementation is changing pmove->maxspeed and pmove->clientmaxspeed before PM_CheckParameters() during noclip and restoring it back when not in noclip. Because it is a cheat command, I don't think it would interfere with anything speedrunning.

Additionally, there could be something extra like "+speed" to double the noclip velocity.
