Added template parameters to the hierarchyParent parser function.

Users can now pass the introtemplate, template, and outrotemplate
optional parameters when calling the hierarchyParent parser function to
customize the output formatting.

Corrected i18n backwards compatibility.

Fixed a bug causing introtemplates to depend on outrotemplate existance.

The introtemplate parameter for the hierarchyParent and hierarchyChildren
parser functions no longer requires an outrotemplate be provided in order
to function properly.

Updated version number from 1.0 to 1.1.
