TypeError accessing Compose view in Plone 5

[hvelarde]

Plone 5.0.5 with collective.cover installed from master branch (1.2b2, unreleased).

After creating a cover object with Layout A, try to access the Compose tab; the following JavaScript error is shown in the console:

21:37:23.653 TypeError: $(...).prepOverlay is not a function

prepOverlay is a method added from plone.app.jquerytools and is the default way to create overlays in plone 4.x AFAIK.

This issue means replace plone.app.jquerytools with other kind of overlay?
