Implement new libsoup cache for >= WebKitGTK+ 1.3.11

The web cache extension is automatically hidden/ disabled if
WebKitGTK+ is new enough, the new cache is a core feature.

By default 100 MB of pages can be cached on disk.

The 'Applications' preference tab is resurrected.

The same folder ~/.cache/midori/web is used for old and new cache.
