send button is now not enabled until after estimates have been selected, but it still enabled if you send all selected estimates and that becomes empty. klbrann
Fixed the race condition where users could vote on a game that had been edited, so long as they had it open before editing began. It now keeps track of versions of games, so this doesn't happen. Modified Game.java and estimate.java, so databases need to be reset to test this. jnallard.
Removed unneeded imports and added comments to new functions, and to some functions missing comments in estimate.java. jnallard
Took out/added appropriate parameters in Javadoc comments, added a couple of Javadoc comments. cjaday
