[IMP] website_event, event: Add event.tag.category and event.tag + rename event.type display name

This commit changes the display name for the model event.type from
"Event Category" to "Event Template"

This change was needed before introducing the new model event.tag.category
which will be used to group tags (event.tag)

This commit introduces two new models: event.tag.category & event.tag

The tags will be grouped by category and will be used to filter events.

In the front-end, if the user activates the "filter by categories", each
event.tag.category will generate a new dropdown of related tags.
Clicking on one of these tags will add a new "tag badge" above the events
(same way as in eLearning).
