Enhance eventtype filtering in eventlistings with a drop-down

[thoni56]

This incorporates the simple change in #64 and adds selection based on names of event types.

Thanks - I tried this locally but just get a text box for event type, not the dropdown:

Have you ensured that the copy of eventlisting.xml in components/com_civicrm/views/Events/tmpl is also updated?

I'm not sure why the files in components need to be there, but it looks to me that, since those copies are not in this repo, they are copied from administrator/... on installation. Unless there is some action during build of the civicrm bundle that I could not find.

Anyway, without the changes also in components/..., what ever XML-definition is there will be used.

At least I hope that is the cause for your installation not picking it up.

Also, I would very much appreciate if you could help me out with how I could test this locally? This repo will not build into a normal Joomla extension that can be installed, and I haven't managed to figure out how to integrate this with a complete CiviCRM build either. So I hacked the sources of an existing install and then extracted those changes to create this PR. Would appreciate any and all help with doing that the correct way.

INSTRUCTIONS for testing:

Copy either the modified files or the contents of the site subdirectory to the corresponding directory under BOTH components/com_civicrm AND administrator/components/com_civicrm/civicrm/joomla/site. E.g.

cp -r .../civicrm-joomla-repo/site/* htdocs/components/com_civicrm/
cp -r .../civicrm-joomla-repo/site/* htdocs/administrator/components/com_civicrm/civicrm/joomla/site
