Raise a NoManifestException when the manifest DNE
When a command (eg, `repo forall`) expects the manifest project to
exist, but there is no manifest, an IOException gets raised. This
change defines a new Exception type to be raised in these cases and
raises it when project.py fails to read the manifest.
