Changes with Aloha.Editor 1.3.23

Bugfix SUP-2201

The sidebar panels of the link-plugin and the ones of the
editing API
have been adapted so that they have a common appearance.

Bugfix SUP-2365

When clicking outside of an editable, and clicking inside on the same element again, the ‘aloha.selection.context-change‘ was not triggered, which for example also prevented the link UI from being activated. This has been fixed.
