LibWebView: Add a settings section to manage browsing data caches

Browse source 
This adds a section to allow users to clear the HTTP disk cache and
cookies / local storage / session storage. There are a few options to
limit this action to a specific time range (e.g. "last hour"). The
user is informed how much disk space is being used currently, and how
much will be removed given the selected time range.

The idea is that in the future, we can add more settings here to auto-
delete data on exit, disable caching altogether, etc.
