I regressed this recently, thinking that all our operators are
strings, but I forgot about the "near:" operator used in the
"Narrow messages around this time" feature. The user facing
symptom was that the search bar showed up empty instead
of saying near:50, which might actually be the better
behavior, but it certainly was not intentional. :)

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/.

Streams are converted to their "official" names now.
Topics are not canonicalized at all.
All other operands continue to be lowercased.
Since we don't lowercase stream/topic at the parsing stage,
we have to modify the predicate function to do the lowercasing
of stream/topic to enable case-insensitive comparisons. This
is slightly more expensive. The server-side predicate
functions are already case-insensitive.

This can be squashed with the prior commit or subsequent commit,
or it can just stand on its own, but it's part of transitioning
to a functional change in the next commit.

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.
