[PATCH v3 0/5] Add submission relations

[Mete Polat]

This patch introduces the ability to view relations between submissions by
creating and updating them via the REST API.

Changes since v2 (note: forgot to mark the previous revision as v2)
- Replace a mistakenly placed tab intention in styles.css with spaces
- Fix typo in commit message header
- Fix AttributeError caused when viewing a patch with no relations
- Remove duplicate 'detailed view' link in submissions.html

Changes since v1:
- Allow cover letters to be in relations as well (submission relations)
- Move from Django permission to a maintainer based one (and update tests)
- Drop bulk support
  I decided to drop the bulk support in favour of an easier implementation,
  usability and maintainability.
- Drop support for manually setting relation id
- Group relations from other projects separately
- Split up UI changes

Mete Polat (5):
  ui: Retain table header position on size changes
  ui, templates: Combine series and related row
  models, templates: Add submission relations
  docs: Add missing series index schema
  REST: Add submission relations
