Tagsearch from a public session

The previous version used a POST request to the server, which is blocked during a public session.
The plugin does not affect the server's state , so the method was changed to GET to make omero-tagsearch functional from a public session.

Advanced filtering features

This release brings UI changes and new features to find objects with tagsearch.

Filtering features:

• Well and Run objects are now included in the results
• Only the tags of the selected user are shown
• Group-wise tagsearch can be done by selecting "All members" in the group dropdown menu
• Tag combination logic can be switched between AND & OR (before that, tags were always combined with the AND logic)
• New field to exclude objects with "excluded tags"
• The tagset of the tags are shown in brackets next to the tag name

Results display:

• Object types can be deselected from the result view
• Turning off the preview now prevents queries from being sent to the server
• The owner of the objects is now displayed in the results

Package renamed to omero-tagsearch

The Python package is renamed from omero-webtagging-tagsearch to omero-tagsearch.
