[Patch] Allow admin to create and delete groups

[Stefan Wallentowitz]

At the current status the plugin only allows to add and delete users to and from groups. In my scenario I want to allow them to also edit the groups themselves.

The attached patch adds a delete button and a fieldset for new group creation.

Since this may not always be what you want the user to allow, you need to enable this functionality in trac.ini:

[htgroupeditor]
allowgroupedit = enabled

I appreciate your feedback

This patch correspondents to my prior patches, a comprehensive description is found at my wiki page.

Wallento, your patch does not apply. I guess that it's because your patch is not based on the 'upstream' version, but on an already modified version. I attach a new version of the patch (LISTrac-htgroupeditor_rebased.patch), which integrates the lines that bring to rejection.
