UI and API improvements for working with large repositories

- Change the tag check bar to only select the current page (by default), but allow for selecting ALL tags
- Limit the number of tags compared in the visualization view to 10
- Fix the multiselect dropdown to limit itself to 10 items selected
- Remove saving the selected tags in the URL, as it is too slow and overloads the URLs in Chrome when there are 1000+ tags selected
- Change the images API to not return locations: By skipping the extra join and looping, it made the /images API call 10x faster (in hand tests)

Fixes #292
Fixes #293
