Executables on Windows have a .exe extension, so don't hardcode gsts-xmlinspect in TARGETS, but let automake figure it out.
Add Makefile.in to MAINTAINERCLEANFILES.
Fix typo in glue/Makefile.am.
Also fix indention everywhere and change code to use Gst.MiniObject.GetObject()
instead of GLib.Opaque.GetOpaque().
It's currently not possible to implement or use GInterfaces on mini objects
but apart from that this should be a great improvement, especially new
mini object classes can be defined in C# now.
