Andrei, this cleans up two warnings about the .svn and pkg.xcodeproj directories
(which apidoc was interpreting as packages). It also has a small update to the
gyp file.

I strongly encourage you to ask me to review GYP changes.

This overwrites the previous value of 'inputs'.  Now apidoc isn't being re-run
as the SDK changes, and neither if dartdoc has changed.

Sorry, my bad. I had noticed that it wasn't being re-run when apidoc.dart itself
changed, which was the problem I was originally trying to solve.

No worries. GYP is so complicated, that's why I really don't mind getting
spammed with GYP changes, as I seem to have a knack for spotting problems :-)

I've already sent you an CL to fix it.
