app_meetme not setting filename and fileformat correctly for realtime

When app_meetme finds a realtime conference, it doesn't get the filename and fileformat correctly when 'r' is set.  Now app_meetme first checks to see if fileformat and filename are declared in the db, if they're not it checks the .conf file, if its not declared there either it then uses defaults.
