fix game commencing message not being called when we want it to be

slightly increase the delay before we refresh the readylist when players
enter the server.

updated admin flag checks

updated welcome message to print how to ready up, since some people were
getting confused

disabled banning people for most things, only temp ban when users get
kicked with .votekick, and if they don't join a team while the game is
live.

initial start on allowing more than 8 maps in the map vote menu, I'm
thinking 21 is a good number since it's 3 full menu pages of maps to
vote for.
finish up supporting more than 8 maps for map vote menu

limit is now hardcoded to 21 maps (3 full pages)

do not insert the same map more than once into the map vote menu

give players a couple extra seconds of map voting time, so they can go
through menu pages.
bump version to 1.6
