Edit QuoteForm, add "ordered" filter, change "Quote" to "Clip", new logos

-Edited quote_create and quote_update so no bugs appear when using
quote_update (but previous tech debt from the typeahead widget remains)

-Added the "ordered" filter to the episode page, to sort quotes on
episodes by time_quote_begins

-Changed "Quote" in the UI to "Clip", but did not change any instances
of "quote" in rest of code.

-Added new logos
