Inline/horizontal setting for checkboxes and ratiobuttons

[bjarnef]

When rendering checkbox or radiobutton lists the options can be listed vertically, but when there are only 2-3 options some may prefer a setting to render the inline/horizontally instead.

Example:

Good suggestion @bjarnef, thanks. We'll have this available as an option on the field type and rendering update in the themes that ship with Forms in the next minor releases.
