Team mods 8/29/16

The php team code has been updated to streamline the processing and perform some error checking as follows:

. the team file is read line by line
. the first line must minimally contain “team:team name” (price type default it “normal”)
. checks to see if UID is a member of any team
. if yes, it updates (overwrites) the record with team name, role, price type
. if no, it creates a new recrod with UID, team name, role, price type
. empty lines are disgarded
