CORE-4426: 
Removed unused class
CORE-4015:
* Updated editor views to support cancellation of saving based on editor
errors.
CORE-4640:
Added Gecko-specific handlers to control the 'grabbing' aspect of the
ui.
CORE-4623 Fix for cmd-line order editing.

Added an AppsIntegrationView#flushRawApp method.
Updated AppsIntegrationPresenterImpl to use this method when building the list of arguments for the CommandLineOrderingPanel, since the AppsIntegrationView#flush method returns a copy of the App, so changes to the argument orders were not persisted between flushes.
CORE-1848:
* Added contextual help to app item category headers.
CORE-1848:
* Added contextual help messages for default argument labels
CORE-4623 Removed Unordered grid from CommandLineOrderingPanel.

Support for unordered Arguments is obsolete, so the unordered grid in the CommandLineOrderingPanel is now obsolete as well.
CORE-4648 Updated orderingRequired for new output types.

Updated AppsIntegrationPresenterImpl#orderingRequired to check for the new, individual output ArgumentTypes, rather than the old Output ArgumentType.
CORE-4640:
* Ensured that App template property editor is not displayed in
"Details" view
Updates for AppsWidgets display strings from I18N.

Refactored the GWT.create call in AppsIntegrationViewImpl to use the static accessor for AppsWidgetsContextualHelpMessages in the I18N class instead.
CORE-4640:
* Ensured that all context help tool buttons are the "circle q"
