clutter-1.0: Upgrade to 1.4 - latest stable version
* Use tar ball release rather than git, as it is more stable. Added dependence
on gettext, and one patch to fix the cross-compile failure due to
conformance-test.
* configure "--with-json=check" avoid extra dependence on external json lib.
* rename examples package (clutter-examples-1.x => clutter-1.x-example) to lead
the right deploy package name
