Stop throwing an exception when an br.extend() or br.implement() points
to a non fully-qualified class, since it isn't a requirement that it has
to.
Changes to UnresolvableRequirePathException that allow the source
require path to be added later, for cases where this information isn't
known at the point where the exception needs to be thrown, but could be
added later on.
Added library manifests for all thirdparty libraries that don't have a
'bower.json' or 'package.json' files -- these files should really be
empty, but we don't currently support that.
Renamed 'browser-modules' to 'bootstrap', and made it an implicit
dependency of the new bundling code.
