'and' has precendence over 'or'.
both operators are left associative
parenthesized expressions are evaluated first
Parser refactored, parseAtom split up.

Use generic queries instead of specialized index queries. This is a step
towards the publisher app, because its client will have to use generic
queries.

We still can't find their width/height or thumbnail the, but at least
we don't wedge the UI now.

Previous value of 1.6 was too small because iPhone 5's aspect ratio
is 1.78, meaning all landscape iPhone 5 photos were included in
is:pano. Same with Moto-X and probably other newer phones.
I tried 1.8, but it still "felt" too small. I think the correct
value is atleast 2.0, but perhaps larger. I don't have enough test
data in that range right now to get a good feel for it.

Add disc and mediaref (a hash of the audio portion of the
file).
Also relocate taglib code to
third_party/github.com/hjfreyer/taglib-go.

Add the title:foo operator to search, to search permanodes which have a
title containing foo, case insensitively.

Provides support for case-insensitive string comparisons.
The implementation needs work (e.g. substring searches do
potentially-large allocations).

Searching for permanodes with zero values for an attribute
returned no results due to a check that at least one value
matched. Only perform that check when a value constraint was
provided.

Work in progress, but works enough to commit now. Determing the time
of things has many TODOs, and there's some performance work to be done
(although it still appears to be instant... it just uses more CPU than
it should)

Also support Width and Height constraints on raw search (not yet
exposed to the expression syntax, but will be like width:<640 or
height:100-200 probably)

Search expressions (e.g. "tag:funny location:Portland") can now be
evaluated server-side (expr.go and expr_test.go, still nascent). Next
step is to remove this parsing and construction from the javascript UI
code.
In addition, the search result now contains a continuation token to
continue interating through the result sets in a subsequent query.
The Javascript UI should use this now instead of parsing out
modification times of things and altering the search. If there's no
continuation token, that either means the end has been reached, or
that search type doesn't [yet] support iteration. Currently only
permanode-based queries are supported at many layers, including
continuation, but will be implemented later.
For now, the web UI should send a search query "expression" value of
non-zero length but just whitespace (like a single space: " ") to get
the home page (recently-modified permanodes") because setting both to
the zero value is an input validation error. We should probably make
an expression operator to be more clear here (like "want:permanode
sort:recent"). But the empty space hack works for now.

And quiet noisy logging on normal write failures.
We can now stress test the thumbnail generation by setting
CAMLI_DISABLE_THUMB_CACHE=1 which will make all the thumbnails in the
browsers be unique, and not write them to cache on the server.
Then, when we're happy with the thumbnails, we just increment the
thumbnailVersion string and that busts all the browser- and
server-side caches.
