* Add a Bundle::Ikiwiki to the source for use with CPAN to install *all*
the modules ikiwiki can use.
* Add a cpan directory containing a CPAN::MyConfig that can ease use of
CPAN to install in a home directory on shared hosting providers.
* With these changes, it's pretty easy to install onto nearlyfreespeech.net
and probably other shared hosting providers like dreamhost. Added
a tip page documentng the process for nearlyfreespeech.
