Serialize dictionaries adding newlines between key-value pairs
Serialize group lists also with newlines in between
Serialize string properties escaping only " and \ (needed for a good diff experience with built-in scripts and shaders)
Bonus:
Make AnimationPlayer serialize its blend times always sorted so their order is predictable in the .tscn file.
This PR is back-compat; won't break the load of existing files.
Cherry-picked from 7dbb1c0571
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!

<reduz> Akien, I understand the need for the second loop mode, but I think
the current UI is pretty confusing. I think this should be changed for an
enum, both there and in the animation.. otherwise we should revert it
[...]
<reduz> alternatively this could be added per track, which I think should
make it a little less confusing
Reopens #959..
Now the AnimationTreePlayer filters for Blend2 and OneShot nodes
behave as expected, that is the main animation is not affected by
the secondary animation if the track is filterd out for arbitarily
complex trees.
Discrete value tracks don't update every frame (only when a new key is
reached). So we can't use the actual property value as an accumulator:
it will end up being zero most of the time.
The _process_node function (which recurses through the blend tree
generating blend values and the active animation list) had an argument
named `switched` which would loop an animation back to the beginning if
it had reached the end (regardless of whether or not it was supposed to
be a looping animation).
This argument was only used in four places: two of them were overridden
by a seek-to-zero, and I believe the other two are bugs.
In OneShot, it was used to reset the oneshot animation to the beginning
when fired. But this would fail if the oneshot node was fired before it
had completed its previous run. While this *could* be a valid way for
oneshot to work (firing does nothing if it's already running), the code
currently resets the fade-in, so I believe that it is intended to reset.
I replaced this usage with seek-to-0.
In Transition, it was used on the previous (fading out) animation when
seeking the Transition node, which I believe is incorrect: why would you
want to loop a non-looping animation instead of simply fading out from
the end? Also it will never happen unless you seek the Transition node
twice during one cross-fade.
The other two uses are in Transition and _process_animation, where it is
used along with a seek-to-zero which overrides it.
