I'm trying to move well-isolated methods out of narrow.js, so that
narrow.js is more strongly focused on UI/ajax interactions and
big, heavy lifting stuff. The logical home for parse/unparse
seemed to be Filter, and they brought along two private methods
with them. The big code moves involved trivial follow ups
like s/exports/Filter/.

1) The class Filter now lives in its own module.
2) The function canonicalized_operators() is now a class method on Filter.
3) The function message_in_home moved to filter.js and became private.
4) Various calling code had to change, of course.
5) Splitting out Filter helped simplify a few tests.

There are also one or two places we don't need to use it for security
purposes, but we do so for consistencey.

If you entered "stream:Denmark " in the search box, we would show
you two suggestions for "stream Denmark", despite our duplicate
detection, because we didn't canonicalize the suggestion that is
literally based off the user typed query, and so the other way
of generating the "stream Denmark" suggestion created a duplicate.
Now all the suggestions we generate are canonicalized, so the
generalized duplicate detection can work.

We now only suggest "Home" if you have an empty search box (suggestion #1),
or if you are typing "Home". Before we'd show it as a way to get back
from various narrows. This is trac #1596.

Moved 400+ lines out of search.js into search_suggestion.js. This
leaves search.js primarily responsible for lots of little DOM
interactions, whereas search_suggestion is more about data.
