- Consolidate structure and content row editing cancellation code into a single function in each class
- Tweak NSTableView subclasses to catch presses of the Escape key and ask the class to abort row editing. This makes Esc key behaviour much more consistent, and allows cancelling/reverting edits made via the mouse (eg checkboxes, dropdowns, enums), or after the cell editing has finished but the row is still selected. - Remove debug - Update localisable strings
