Added use of more accessible tags to create tabbed-interfaces then
updated css and JS to require use of those attributes rather than custom
techniques.
Updated relevant parts of app.
Some custom parts using their own tabs though, something to improve in
future.
Old system was hard to track in terms of usage and it's application of
'components' properties directly to elements was shoddy.
This routes usage via the components service, with element-specific
component usage tracked via a local weakmap.
Updated existing found usages to use the new system.
- Updates old components to newer format, removes legacy component
support.
- Makes component registration easier and less duplicated.
- Adds base component class to extend for better editor support.
- Aligns global window exposure usage and aligns with other service
names.
- Created new dropzone component.
- Added standard component event system using custom DOM events.
- Added tabs component.
- Added ajax-delete-row component.
