Allow setting of the user image style in widget settings

Will try to implement this.

I have a working patch I will submit

MR125 Adds a setting in the field widget for avatar image style.

Hello @loze,

I have applied the MR and the image style gets added on the tag image as desired. Attached some screenshots with this comment.

Moving the issue to RTBC.

Thanks @debrup and @loze to work on this.

It will be included in release 1.2.32.
