Add a separator attribute setting for controlling how multiple values for a single attribute are separated:
separator=newline inserts a newline between values, resulting in one value per line.
separator=comma inserts a comma and space between values.
separator=space inserts a space between values.
Any other value will be inserted as is between values, allowing for custom separators.
The default separator is now separator=comma, except separator=space is used for badge and boolean attributes.
Before, the default was separator=newline, except separator=space was used for badge attributes in table views.
Escape sequences are now supported in attribute setting values using a backtick as the escape character: `</code> and <code>\,. This allows for using a comma in settings that accept arbitrary text such as header.
