Update docs to include info about setting dashboard host via module

The current documentation does not reflect the fact that the module
provides a parameter for setting the listen address for the PuppetDB
dashboard.  It mentions that you may need to override the setting
in jetty.ini, but if you do this after installing via the module,
the module will override your setting.  This commit takes a stab
at updating the docs to indicate how you'd accomplish this via
the module.

@nfagerlund: I presume you'll want to reword or entirely gut this
verbiage and work your magic on it, but I just wanted to submit this
as a starting point.

Properly determine version for non-rc commits on top of tags

This was doing the wrong thing in the case of a version number like
1.0.0.16, where the .16 was being completely ignored. Now we support
that correctly, just considering it an optional segment of the version
number.

Fix the link to the PuppetDB module detailed documentation

In a recent pull request I had removed the README_GETTING_STARTED.md file from
Github leaving a broken link in the curated docs.

This patch replaces the link with the forge page, which should be the
authoritative place for these docs.
