Bug 1014 - Clutter Animation API Improvements

	* clutter/Makefile.am:
	* clutter/clutter.h: Update the build

	* clutter/clutter-types.h: Add AnimationMode, an enumeration
	for easing functions.

	* clutter/clutter-alpha.[ch]: Add the :mode property to
	control the function bound to an Alpha instance using an
	enumeration value. Also add six new alpha functions:

		- ease-in, ease-out, ease-in-out
		- sine-in, sine-out, sine-in-out

	* clutter/clutter-deprecated.h: Deprecate the #defines for
	the alpha functions. They will be replaced by entries in the
	ClutterAnimationMode.

	* clutter/clutter-interval.[ch]: Add ClutterInterval, an
	object for defining, validating and computing an interval
	between two values.

	* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
	object responsible for animation the properties of a single
	actor along an interval of values. ClutterAnimation memory
	management is automatic. A simple wrapper method for
	ClutterActor is provided:

		clutter_actor_animate()

	which will create, or update, an animation for the passed
	actor.

	* clutter/clutter-debug.h:
	* clutter/clutter-main.c: Add a new 'animation' debug note.

	* clutter/clutter-script.c: Clean up the alpha functions
	whitelist, and add the new functions.

	* doc/reference/clutter/Makefile.am:
	* doc/reference/clutter/clutter-sections.txt: Update the
	API reference.

	* doc/reference/clutter/clutter-animation.xml: Renamed to
	doc/reference/clutter/clutter-animation-tutorial.xml to
	avoid clashes with the ClutterAnimation section.

	* doc/reference/clutter/clutter-docs.sgml: Renamed to
	doc/reference/clutter/clutter-docs.xml, as it was an XML
	file and not a SGML file.

	* tests/Makefile.am:
	* tests/interactive/Makefile.am:
	* tests/interactive/test-animation.c:
	* tests/interactive/test-easing.c: Add two tests for the
	new simple animation API and the easing functions.

	* tests/interactive/test-actors.c:
	* tests/interactive/test-behave.c:
	* tests/interactive/test-depth.c:
	* tests/interactive/test-effects.c:
	* tests/interactive/test-layout.c:
	* tests/interactive/test-multistage.c:
	* tests/interactive/test-paint-wrapper.c:
	* tests/interactive/test-rotate.c:
	* tests/interactive/test-scale.c:
	* tests/interactive/test-texture-quality.c:
	* tests/interactive/test-threads.c:
	* tests/interactive/test-viewport.c: Update interactive tests
	to the deprecations and new alpha API.
