Add animation_changed signal to AnimationLibrary

Browse source 
AnimationLibrary now listens for the animation_changed signal on its
animations and emits this new signal, with the animation name added
on. AnimationPlayer now connects to this signal rather than connecting
to each individual animation, which was poor practice due to bypassing
encapsulation.

Emitted when an [Animation] is added, under the key [param name].

<signal name="animation_changed">
<param index="0" name="name" type="StringName" />
<description>
Emitted when there's a change in one of the animations, e.g. tracks are added, moved or have changed paths. [param name] is the key of the animation that was changed.
See also [signal Resource.changed], which this acts as a relay for.
