bunch generate ignores packages which are not go get'd

[tamird]

My project depends on code.google.com/p/goauth2/oauth, but bunch generate omits it, which causes bunch go build to fail. Adding "code.google.com/p/goauth2/oauth" to Bunchfile manually fixes the problem, but the entry is again removed each time bunch generate is run.

EDIT: This issue is actually that the package is not currently in my GOPATH. I have a fix on the way!
