LibWebView+RequestServer: Support clearing the HTTP disk cache

Browse source 
This is a bit of a blunt hammer, but this hooks an action to clear the
HTTP disk cache into the existing Clear Cache action. Upon invocation,
it stops all existing cache entries from making further progress, and
then deletes the entire cache index and all cache files.

In the future, we will of course want more fine-grained control over
cache deletion, e.g. via an about:history page.
