Bump version number, fix up CHANGES.
The `Viewer` constructor argument `options.fullscreenElement` now matches the `FullscreenButton` default of `document.body`, it was previously the `Viewer` container itself.

This fixes #1305

This also fixes a copy/paste error in DynamicObjectView which was causing it to not show up in documentation.
