fix undefined array error

Just a note, although not overridden by display, these settings seem to be overridden by type of display. e.g. block, page etc (which is good)

Please open a merge request.

fixes white space

Looks like patches need re-roll as not applying either on 11.x or 10.1.x and may also require rebase to raise the PR.

reworked slightly to:

1. allow classes to be applied to row without need for default classes to be enabled (this assumes the default class is view-content.
2. Allow default container class to be enabled or disabled. The default is to enable.
3. Along similar lines, added support to allow default "empty" container class to be enabled or not. The default is to enable.
4. Reworked descriptions. Explain that custom classes can be separated by space if using more than one.

Previously the custom row class would only work if the default value was selected.
