fixed some errors in the titling for gottalk
tune up on docs, moved higher level specs to features
basic tests of the gottalk form; still have to add the list of 'hot talks'
cosmetic changes
have added stubs for a bunch of searches, esp talks_by_person
added in working code to return anonymous, even if anonymous not present!
fixed up database; started on stories; have one test to clear but first get it pushed to heroku to validate work done so far
