v0.9.2: Window resizing edition

This release fixes some oddities related to resizing the main window and individual sections. The old behavior was OK, but with the addition of the outline view, resizing app sections was a bit weird.

Old Resizing:

Dragging a divider resizes the two sections on either side. Resizing the window shrinks the editor area to a point, and then starts hiding content.

New Behavior:

Moving a divider resizes the two sections on either side, but dragging further continues to resize and collapse adjacent sections. Resizing the window shrinks the editor area, then starts collapsing other sections.
