Updated GroovyDoc to use new templates
Update the package-frame to the same look
Some lowercase tags
add proper body style to help-doc and remove useless hr in index-all
remove mentions of the tree hierarchy as it's not currently supported by groovydoc
remove prev / next in overview
remove prev / next in overview summary
Various fixes to the new styled groovydoc:
- removed all prev / next remaining
- changed pipe characters to space in summary / details for simplicity sake
- use lists instead of tables for package summary
- made headers / footers consistent between pages
Cosmetic: Remove useless dummy javadoc comments left by IDEs
Ongoing changes to get the new groovydoc template adapted
Merge pull request #367 from glaforge/groovydoc-restyled
