Maximize animation panel, rounded stroke caps, and more

New

• Maximize and minimize the animation panel with the backtick shortcut (`).

• Strokes added to paths now default to rounded caps and joins.

• Pasting an artboard will now pan to the pasted artboard.

• Splitting paths now result in an asymmetric vertex rather than a detached vertex.

Fixes and improvements

• Fixed inconsistent behaviors with ping-pong and loop playback in the Editor when using the spacebar versus the play/pause button.

• Fixed a crash with the keyboard shortcut for our super-secret chat feature.

• Can now paste an artboard into an empty file (a file that does not already contain an artboard).
