[Improvements]
- Some boolean options can now be set to PERL_CPANM_OPT but can be negated
using the --no- prefix such as --no-sudo
- Directory mode now only works if it begins with / or .
[Developer fixes]
- --self-upgrade skips if it's already the latest
- Improved perl Makefile.PL --author
- --help and --version won't bother ~/perl5 initialization (rjbs, ingy)
- LWP dependency is injected only if you run from CPAN clients (ingy, marcus)
