js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

ST makes use of GTK+ for input methods and for icon themes; therefore
we have need to initialize GTK+ in order to test these parts of Clutter.
Instead of LD_PRELOADING our module, use a separately compiled executable
that links to the UI components in GNOME Shell, initializes Clutter and
GTK+ and hooks them together.
Getting all the symbols from St and the GUI components exported for
use via GJS requires a bit of contortion: we need to actually link the
St convenience library into a shared library and link the executable
to that since there is no way with libtool to take a convenience library
and put all its symbols into an executable --whole-archive style.

ShellTheme replaces both StStyle and ccss_stylesheet_t.
The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.
Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.
Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:
shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);
The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.
Some more javascript tests for CSS functionality are added; workarounds for
a CSS bug where *.some-class was needed instead of .some-class are removed.

js/ui/environment.js: Split out initial UI setup (Tweener initialization,
ClutterContainer monkey-patching) into a separate file we can import from tests.
tests/: Directory for various types of tests
tests/run-test.sh: Shell script that to run tests with an appropriate
environment set up.
tests/testcommon/: Common modules and data for tests
tests/interactive/: Interactive tests
tests/interactive/box-layout.js: A sample test of StLayout
