As a survey developer I want a more compact styling of (required) radio buttons

[pkuppens]

Surveys with many radio buttons are very long and somewhat ugly in layout.
This could be improved by aligning the radio buttons horizontally.

Also, the 'required' indication, an asterisk glyph, is rendered ugly because it is too big compared to the label. This can be improved by styling it in a smaller and superscript font.

Definition of Done:

1. Horizontal rendering of radio buttons
2. Smaller, superscript indication of 'required' indicator

Out of scope:

1. Radio buttons could also be used for longer, multiple-choice questions and answers, that may need to be aligned vertically.
2. Define a horizontal/vertical align toggle per question
3. The radio button group, where a set of questions (vertically) all have the same radio buttons as possible answers.
