[rt.cpan.org 41437] Add options for server passwords and SSL.

Applly Don Seller's patch from the RT ticket.
[rt.cpan.org 85315] Make cver optional.

Per Axel Beckert's recommendation, the IRC version string is made

can still be overridden in the .conf file, and all existing
installations will continue to work the way they always have.
Add an example configuration for web pastebin-only use.
Initial conversion to Dist::Zilla.
Superficially document internal modules for Dist::Zilla's sake.
Merge branch 'master' of github.com:rcaputo/bot-pastebot into gh
