New features

Initial commit for dev release

Major change: Modified how data is saved on the system. Only ag-Grid rowData will be applied to each content item for field. Headers and any additional options will be pulled from the ag-Grid config entity.

• Issue #2973939: Content field should only be collecting the actual data, not also the head

Changes since 7.x-2.0-alpha1:

• Fixed broken token in #2372919: Edit email with group token
• #2773253 by rjjakes: Impossible to translate a string
• Added multiple_email integration
• Removed roles selection element when no roles to select

Support for ignoring leading numbers in pattern file names and parsing documentation from markdown files.

Fixes #2958294: Payment

Fixed a bug with config entity create. Also added a simple demo module.
