Remove release methods from catalog.complete

They are unused (and were accidentally introduced in 0.9.4 with the
sqlite branch).  The only thing you're allowed to query for releases is
the official catalog, since the complete catalog doesn't actually
augment releases with anything.

(If we later implement some sort of "local release", we should probably
also introduce a new release-specific interface that can be backed
either by sqlite or by sqlite-plus-local, analogous to catalog.  There's
no real reason that it should be the same interface as catalog.)
Isopack.saveToPath doesn't always need a capture

It should only need a capture if you need to include
buildinfo. Specifically, the use in tropohouse for package merging
should not be able to fail with a buildmessage.

Failures to statically compile packages for the tool now just crash the
tool, just like uniload failures. This should never happen unless you're
working from a checkout and have broken a core package.
Remove duplicate method definition

There's another isLocalPackage lower in the same _.extend, and that's
the one that is being used.

Update Node to 0.10.33 from 0.10.29

Our npm patch is not yet in a Node 0.10 release (it's in npm 2.1.0).
Explain why not upgrading fibers
Explain why not upgrading underscore
upgrade source-map-support: 0.2.8 (from 0.2.5)
Upgrade semver to 4.1.0

I believe all the backwards-incompatible changes are to features we
don't use, like range expressions and the inc function.
Upgrade request to 2.47.0 from 2.33.0

Looks like it now auto-detects $HTTP_PROXY so we could drop that code
from http-helpers (but not from the faye stuff).
Upgrade tar to 1.0.2 from 1.0.1
