==================== Summary ====================

Name: Morphic-dtl.609
Author: dtl
Time: 11 February 2012, 12:07:02.836 pm
UUID: 7e071de6-1409-44f1-aedb-e3f18075810d
Ancestors: Morphic-cmm.608

Make Connectors removable (almost).

Morph>>connections and Morph>>wantsEmbeddingsVocabulary are provided by package Connectors. Remove the stub implementations from Morphic and update Morph>>wantsConnectionVocabulary and Morph>>filterViewerCategoryDictionary: in package Etoys with #respondsTo: checks to break the package dependencies.

Allow Morph>>dismissMorph override to be removed from Connectors by adding the functionality to package Morphic, guarded by #respondsTo:

Follow up needed in Connectors:
Remove Morph>>dismissMorph override
Remove PasteUpMorph>>tellAllContents: override
Remove ObjectPropertiesMorph>>rebuild override
