It should be easier to customize/plugin to the existing edit popover

[panphora]

The default Remake edit popover (that pops up when clicking an element with an edit: attribute) has default styles applied to it and can't be customized a lot.

It would be nice if a user could make a custom edit component and insert it into the edit popover.

This will probably require some thinking around how Remake can support a plugin architecture in general.

There are already some plans in the works for supporting checkboxes and radio buttons the edit popover. But advanced image uploading and cropping control would be a great additional plugin that probably wouldn't be in the core Remake library.
