Cleaned up some find PlayerInfo code

Made it so the code from /info that finds the playerinfo does not have
to be repeated in the code multiple times
Fixed findgeoip (3rd times the charm?)

Should no longer error if a player logs off before the geoip information
is shown.
Added unused MySQL support

Might find a use for it someday, so just gonna leave the unfinished
commented code in here for now.
Updated README.md
