This is a big commit that introduces two to-die-for features into
Banshee. First is a generic GTK WebKit-based embedded browser, called
OssiferWebView, which extends WebKitWebView. OssiferWebView is written
in C, because it makes fairly heavy use of WebKit and Soup APIs, for
which the C# bindings are rather lacking. A simple, easy-to-bind API is
exposed. In C#, Banshee.WebBrowser.OssiferWebView is available for
extensions to use for embedding a reliable web browser.

GTK WebKit 1.2.0+ is required. Fortunately, this is very easy to build
on openSUSE 11.2-era systems.

What is most important though, is the introduction of the
Banshee.AmazonMp3.Store extension, which leverages
Banshee.WebBrowser.OssiferWebView to provide an integrated and dedicated
Amazon MP3 store browser. Music can be browsed, searched, and purchased
in Banshee just as you would through Amazon MP3's web site in your
regular browser, however there are two (current) user experience
improveme...
