edit 7.x-1.0-alpha7

This release brings the Drupal 7 & Drupal 8 versions of Edit in sync as much as possible. It fixes many, many bugs.

Changes since 7.x-1.0-alpha6:

• #1900436 by Wim Leers: Fixed Critical regression: Untransformed text no longer retrieved (causing the user to edit the filtered text instead o/t source text)
• #1947656 by Wim Leers: Fixed Clearly document how to configure CKEditor to get in-place WYSIWYG editing up & running
• #1906490 by Wim Leers: Fixed Default CKEditor toolbar used instead of the CKEditor profile because toolbar configuration not a JS Array
• Bring D7 & D8 Edit in sync.
• Reverting ce7d08a886bafef96cbdf964b1c9db6ca89cb0ec (for issue #1893638), because it's a hack that doesn't work (anymore). See issue for details.
• Follow-up for issue #1830518, commit 1206b74bcf24964df30e5c1cf42d6a3aeb119813: remove unused CSS, document edit_wrap_pseudofield().
• Follow-up for issue #1891246 by Wim Leers: now modifies the correct piece of CSS, and removes Drupal.edit.views.PropertyEditorDecorationView._getBgColor(). Also reverts f51d1ed9ea619245ece4527ac63c982656906eef, which clashes with these changes, because it doesn't work anyway.
• #1931766 by Wim Leers: Fixed README is wrong: core patch must still be applied when using Drupal 7.20
• #1935024 by Wim Leers: Permissions are double-checked/render cache is broken by only conditionally adding the data-edit-id attribute
• #1935032 by Wim Leers: Fixed Edit's "Quick edit" toggle render array + unclear handling of metadata loading + lack of code docs
• #1935004: Settle on "in-place" editing instead of occasionally also using "inline" editing.
• #1902882 by swentel: Fixed Notices triggered in edit_metadata_generator().
