startup.blend Theming/AnimEditor Defaults Tweaks

- Default size of Graph Editor handle vertices is now 4 (up from 3).
This "small" change seems to be enough to make a substantial
difference when it comes to actually differentiating between these

- "Only Selected" DopeSheet filter is enabled for new Graph Editor
instances by default. It helps hone in on the F-Curves of the data
most animators hope to just be refining the motion for (i.e. the
selected stuff)

- "Only Selected Keyframe Handles" is now enabled, to reduce clutter
from handles of nearby keys getting in the way.
