Album view

[damianmoore]

Following on from #299 where album (A type) tags got assign in batch to photos, we now need to display those photos.

@GyanP Please create your branch off of new-ui which should have your latest batch operation code merged in by the time you read this.

• In the floating Tabs component add a new tab labelled Albums between Timeline and Map.
• Make the tab link to /?mode=albums.
• Create new GraphQL endpoint that returns albums (tags of type A). These results should be sorted alphabetically and contain:
  • Tag name
  • Tag ID
  • Number of photos that are assigned this tag
  • Cover image (most recent photo that was tagged with this album tag)
• The Albums view page should look the same as timeline but show the albums returned from the GraphQL query above.
• Clicking on an album will not take you directly to a photo but to /?mode=albums&album_id=07473ff9-7395-4a43-9163-e8da016d5ce7 which then shows more thumbnails.
• Data for photos within an album can be fetched using the main GraphQL query that uses multiFilter as the selected album will just be tag filter as we have already done.
• The search bar needs to still work, i.e.
  • Typing a partial tag name will reduce the albums listed (but dropdown shouldn't display)
  • When an album is selected the dropdown should work again and should filter photos by tags etc. as in timeline view.
• On timeline, user should be able to select multiple photos and then "Add to album" option which has text field like tags
  • 
• When viewing thumbnails in an album, user should be able to select multiple photos and then choose from "Delete from Album" (which removes from current album or "Add to album" which shows option window for adding tag for another album.
