hoc2015: improved success checks for levels 10 & 11.

In level 10, if you get all the characters, and don't have enough points, we fail immediately, so the student doesn't have to wait for a timeout.

In level 11, if you don't add three pufferpigs, then we fail immediately.  We also check for getting three pufferpigs, specifically, so the student can add other characters if they want, but have to collect three pufferpigs in particular to succeed.
