Experimentally add build infrastructure and a few Tidy widgets

Browse Source 
For experimenting with using tidy, import TidyButton and TidyGrid
(+ dependencies) into our source tree and set up build machinery
to build them and build a typelib for them.

The sources are build right into libgnome-shell.so, so the Shell.gir
and Tidy.gir actually point to the same shared library.

src/Makefile-tidy.am: Build libtidy-1.0.la
src/Makefile.am: Include built tidy into gnome-shell.la and
  build Tidy-1.0.typelib

* @short_description: Interface for stylable objects
*
* Stylable objects are classes that can have "style properties", that is
* properties that can be changed by attaching a #TidyStyle to them.
*
* Objects can choose to subclass #TidyActor, and thus inherit all the
* #TidyActor style properties; or they can subclass #TidyActor and
* reimplement the #TidyStylable interface to add new style properties
* specific for them (and their subclasses); or, finally, they can simply
* subclass #GObject and implement #TidyStylable to install new properties.
