Multiple resource tags

[AristurtleDev]

If a resource listed has more than three tags, then the tags wrap around and can get crowded.

Here is an example, with 7 tags

This PR adds logic to the resource.njk template to

• When a resource contains more than 3 tags, a 4th element is displayed with just the additional number of tags (e.g. if a resource has 4 tags, the element will say "+1"
• When the 4th element is hovered, a tool tip is enabled that lists the additional tags

Here is a video example of this in action
