Help: Edit Event lineup method

This is for automatic tournament management (automatic court and match-queue management).

Event lineup method: The way events lineup for match queue.
The default option is Court permits. The options are:

All in session: All events will enter match queue unconditionally (one after another). This option will generate longer waiting list of match queue. A player will wait longer for the next match, but can see his/her position in the waiting list of match queue.
Court permits: If all courts are assigned and no courts available, an new coming event in the event queue will not enter the match queue. Later, when there are empty courts, the new coming event will automatically enter the match queue.
This option gets short waiting list, so a player will wait short time for the next match. Players in new coming event will wait to see they are in the waiting list of match queue.
