Suggestion Title (What are you Suggesting):
Increase sv_maxvelocity (or set it to 0 for no limits)

How / why would it benefit the Surf server:
- Some maps have boost (as mesa) but they are useless because of the limit.
- The unreal mode is currently limited because of the current value of sv_maxvelocity, setting sv_maxvelocity to 0 would be a big benefit for this mode

Potential Issues/Exploits:
On some maps yes, we will certainly be able to skip some parts. (But hey, new wrs to break!)

Additional notes:
Currently, sv_maxvelocity is equal to 4000
Why a limit is needed anyway
