Battle fix

-Fix battle invade/duel - the page layout changed a while back apparently, and as a result, Battle invade or duel only read the first target
-Reduce battle invade/duel refresh frequency - with the default set up, battle would mash the refresh on the battle page up to 20 times in 45 seconds when looking for new targets, despite new targets only appearing once a minute. We want to avoid this kind of load on the CA servers. I reduced to two refreshes per minute.
-Fix for FB not loading due to hyper function not defined
-Fix for hyper default local storage entry not having outside parentheses
-Fix for NaN setting sometimes for max stamina or energy
