Fix table plugin losing the drag handle upon getContents() of the editable (e.g. in smart content change).
To fix this, the makeClean() method does not deactivate the tables in the given DOM structure any more, because this would unblockify the table in the editable.
Instead, aloha/ephemera is used to mark all DOM elements, classes and attributes that are added to the table for making it editable.

Fix several issues with the cite-plugin (handling blockquotes).
Pressing backspace in blockquotes will no longer wrap the blockquote into a div.
Pressing enter at the end of a blockquote multiple times will now create a new paragraph after the blockquote (similar to lists).
When blockquotes and quotes are nested the controls will now show the correct status.
