Title: Document the '--skip-installed' option

This option is mentioned by `--skip-satisfied` but doesn't appear to be documented anywhere in the manpage. I've also added a note about `PERL5LIB` that may help solve some confusion about how it works (see e.g. [#649834](http://bugs.debian.org/649834)).

In the same bug report was also asked whether cpanm could set `PERL5LIB` to a default value (e.g. `~/perl5/...`) if it finds that it isn't set. What do you think?

Cheers
