Save user preferences

[matthew-white]

The user can make a number of selections/choices in Frontend that we've talked about persisting. We've talked about persisting them server-side. Some preferences seem to be top-level/sitewide, while others seem per-project. We already have sitewide settings (for usage reporting), project settings, and form settings. However, those are not specific to the user. This issue is about saving individual users' preferences.

Top-level/sitewide preferences to persist:

• Whether the top panel on the homepage is shown or not
• The sort order of the project list

Project preferences:

• The sort order of the form list
• Whether the form trash is shown or not
• Whether managed or legacy QR codes are shown for app users
