======================
SV_Map_f

handle a
map <mapname>
command from the console or progs.

quirks:
a leading '*' means new unit, meaning all old state is flushed regardless of startspot
a '+' means 'set nextmap cvar to the following value and otherwise ignore, for q2 compat. only applies if there's also a '.' and the specified bsp doesn't exist, for q1 compat.
just a '.' is taken to mean 'restart'. parms are not changed from their current values, startspot is also unchanged.

'map' will change map, for most games. note that NQ kicks everyone (NQ expects you to use changelevel for that).
'changelevel' will not flush the level cache, for h2 compat (won't save current level state in such a situation, as nq would prefer not)
'gamemap' will save the game to 'save0' after loading, for q2 compat
'spmap' is for q3 and sets 'gametype' to '2', otherwise identical to 'map'. all other map commands will reset it to '0' if its '2' at the time.
