stylecontext: Only create transitions conditionally

Browse Source 
While regular animations should always be created, transitions should
not. This patch allows to express this by passing NULL as the values to
transition from.

It also adds a gtk_style_context_should_create_transitions() function
that returns TRUE when transitions should be created.
