Inconsistency between Long Text and Content fields display in AWM wizard and entries

Steps to reproduce:

1. Create a new app with AWM
2. Add 2 fields from the Palette on the right: Long Text and Content:
3. Configure the editor from Administration to use Text, GWT and CKEditor
4. After each editor is set, go to your app and edit it

Actual result: The display is different for these 2 fields each time a new editor is used.

Expected result: I see 2 possibilities. We need to display the same editor both when creating an app and also when editing it:

1. use the editor configured globally or the one set in the user's profile
2. use the Plain Text editor by default, disregarding the configured editor

I would go for option 2 since it uses less resources and we don't really need to load the editor when editing an app.
