[PATCH v4 9/9] templates: Add "download series" links

[Stephen Finucane]

This will allow users to download entire series including the current
patch. Since a patch can belong to many series a dropdown is used.

Signed-off-by: Stephen Finucane <stephen at that.guru>

v4:
- Don't use a dropdown when only a single series is available
v3:
- Add unit tests
