Iss #77 - Add EF look and feel template into auto-loaded tags template

A new eclipse_base template has been added that makes use of the eclipse header and footer files that already existed, and adds a few basic overridable sections for flexibility. As part of Quarkus configs, the templates/tags folder for Qute templates is auto registered as a source, meaning that this will be available to consumers of the core package.
