comparison of correctness in multiple choice.

Multiple choice code is scattered and sometimes sends a list of
choices for the value, and sometimes a single string. We used to use
"in" which scarily handled both cases (list or substring search),
but that caused a bug when you had two choices like choice_1 and
choice10. Moving to == caused us to break when lists were sent to
us. So this ugly code is extra paranoid and checks both possibilities.

This really needs a better cleanup.

Remove the default and prevent input_state from persisting across problems

unnecessary data.

Fixed bug in parsing of urandom struct so that seed

Fix/cdodge/use request scoped cache for metadata inheritance

hmmm. actually, we should only write out to memcache if we've recomputed. Otherwise, a memcache hit will end up writing back to memcache...

use a request-scoped cache to keep the metadata inheritence tree around for the whole request. This means we should only do one trip to Memcached/Mongo per course per request. This is expected to keep memory utilization down
