Update init.pp

Added $stanza variable and changed module to use that to build the changes. This solves the problem of not being able to modify the same stanza in two different conf files. This is an issue when you have Splunk and Universal Forwarder installed on the same box and want to edit the web.conf for both, for instance.
Update splunk.aug

Updated augeas lens for Splunk to latest version from original author's github repo
Update Modulefile

Updated version to 0.1.1 to reflect my changes
Make stanza optional, to work like stock types

Generally, if the stanza is the title/namevar, then the stanza parameter
itself is unnecessary. Also, add parameters to inline docs.
Add glue for green field development

That is, for a host which does not have the Splunk lens sync'd somewhere
else.
