More verbose errors for NoManifestExceptions.
The old "manifest required for this command -- please run
init" is replaced by a more helpful message that lists the
command repo was trying to execute (with arguments) as well
as the str() of the NoManifestException. For example:
> error: in `sync`: [Errno 2] No such file or directory:
> 'path/to/.repo/manifests/.git/HEAD'
> error: manifest missing or unreadable -- please run init
Other failure points in basic command parsing and dispatch
are more clearly explained in the same fashion.
