[svn] * src/noffle.c: Rearrange initialisation so that a requested usage message will be output before Noffle can fail due to misconfiguration. Introduce routine (currently stub) for checking file ownership and permissions on startup - I suspect a lot of reported errors are due to ownership problems.

To build an RPM for version m.n release r, set Version to m.n and Release to r.
Then rename the noffle directory to noffle-m.n, and make a compressed tar
noffle-m.n.tar.gz.

Run 'rpm -ta noffle-m.n.tar.gz' to generate binary and source RPMs.
