Goodbye Perl6::Bible. Hello Perl6::Doc.

Ralf and I seem to have discovered independently at nearly the same time that the Perl6::Bible "module" is finally being replaced with Perl6::Doc. I have a perl-Perl6-Doc package sort of ready, but I am not sure what to do about a few things.

1. Do we bother to obsolete the perl-Perl6-Bible package? I wouldn't be surprised if I was the only person who bothered installing it.
2. If we obsolete the perl-Perl6-Bible package, should we symlink the p6doc script to p6bible on the off chance that anyone was using the p6bible script?
3. What do we do about the name conflict with the p6doc script included with Pugs?
