updated to prompt for number of players in game. Now only works for 1
player. DB Table 'games' entry created & new commands for table 'games'
is in the db.sql file (just two lines needed).  (Currently, after adding
1 game entry, entry must be erased before rerunning).

idea is to have DB updated with current status of games...mainly for
queueing the waiting games until they have correct number of players.
Subsequent players should cause db lookup/update & when all players
present, need to notify all players quiz is about to start.
