[spice-xpi 9/9] Switch to using npapi-sdk headers rather than XUL

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Using the XUL SDK to build a plugin is quite overkill as all that
is needed are a few headers. Using these headers means less dependencies,
which makes things easier to build spice-xpi on other platforms.
