Bugfix: check list rules weren't getting removed when you removed the taxon.
Added site-specific results to projects/browse.
Bugfix: user search api was returning all users regardless of query when signed out. Closes #384.
Bugfix: adding obs to project w/ fields was only adding fields

When you add to a project on obs/show and the project requires
observation fields, you see a popup prompting you to fill out the
extra fields. However, despite the fact that the fields were getting
added, the obs was not getting added to the project. I suspect this
was lost in 4328274.
Added more kinds of project rules, OR project rule combos.

The OR stuff: if there are multiple project observation rules with the
same operand, project observations will be valid if they satisfy
either rule. So if there are rules for must be in Amphibia and must be
in Reptilia, the project will accept observations of reptiles OR
amphibians.
Some minor bugfixes.
BUGFIX: I broke taxon project obs rules.
Bugfix: obs caches weren't site-specific.
Site-only top identifiers on obs/id_please. Closes #391.
