Improvements to manage kits

[oscgonfer]

Linked to some of the minor improvements on the kits page on the user profile (#443), this issue is to map potential improvements we can do on the KITS page of the User profile.

Ideally, this page should be called "Kits management" or similar (TBD), but could allow a better functionality for users to do batch operations on the kits:

• search
• sort (multiple properties: name, last_reading_at,... )
• filter...

Best case scenario, is that we have something like a combination of list.js with more advanced functions, that allow people with kits to, for instance:

• Export data in bulk via email
• Add/remove tags in bulk
• Change the exposure
• Change location
• Make private
• Change notification settings
• Export a basic CSV with information of those kits (such as the one in the dashboard
• Delete (?)
