Assessment labels

[rabstejnek]

This PR adds label functionality to assessments, where labels are able to be applied to visuals, data pivots, and summary tables. These labels are visible on detail and list views, and are able to be filtered by on these list views.

---

A label can be created on an assessment with a name, color, description, parent, and published status.

---

Creating multiple labels can lead to a tree-like structure with the use of the parent field.

---

Validation is in place to protect the integrity of the tree when assigning a parent and also with the published status, since an unpublished label with published children would break the tree if a user is not able to view unpublished labels.

---

Labels can be applied on the detail views for visuals, data pivots, and summary tables.

---

Once applied, labels can be viewed on detail views.

---

The labels can also be viewed on the list views.

---

Objects can be filtered by label in these list views.

---

Filtering by label also includes the subtree, so since "second label" is a child of "first label", objects labeled with "second label" are included when filtering by "first label".

---

Users without sufficient permissions to view published objects will not be able to see unpublished labels assigned to objects.

---

Add a filterable label list view

Wonderful job. I made a number of edits, mostly moving code around. I also reorganized the visual list and table list views; when a visual had a long caption which is commonly the case the one-line view didn't really work.
