GridfieldExtensions' GridfieldOrderableRows is functionally quite similar (if not identical) to GridFieldSortableRows, and not all developers may want to support both modules. This commit adds fallback support for sorting Document Sets using GridfieldOrderableRows if it is installed, and GridFieldSortableRows is not.
To test:
1. Uninstall GridFieldSortableRows (or start with an install without it)
2. Install GridFieldExtensions
3. Create/Open a Document Set
4. Make sure there are multiple files within.
5. Drag/drop reorder without errors
* Remove "small" class from inline edit form for documents
* Swap relationeditor GridFieldConfig for record editor to ensure that document sets can be deleted from a page context rather than unlinked (natively)
* Fix to ensure that related documents can be autocompleted via partial matching on filename
* Add 2 space indentation rule to editorconfig for .js and .scss files
* Add 2.0.0 changelog
* Update DMSInterface and DMSDocumentInterface removing *page and adding getDocumentSetsByPage to DMSInterface
* Update use documentation and update unit tests
This commit changes the relationship from Pages has_many Documents to Pages has_many DocumentSets which are many_many to Documents. The upload field has been upated to attach documents to a set instead of a page, the tests updated and the DMSInterface and DMSDocumentInterface updated to be less relevant to pages and more relevant to document sets.
