Wizard and Werewolf spawn tweaks for rp

[Lord_earthfire]

Weaith soawnrate is very loathed at because it is really really low. While yes, they could spawn a but less, that's the possibly worst comparison to make.

But overall, i don't mind them being somewhat rarer.

The problem is mostly the low amount of antags in general on RP. Having a single wizard with 1 other antag feels odd, although it is just a result of chance.
