Text formatting in OpenSesame

OpenSesame supports a sub-set of HTML tags:
- <b>Bold face</b>
- <i>Italic</i>
- <u>Underline</u>

In addition, you can pass 'color', 'size', and 'style' as keywords to a 'span' tag:
- <span color="red">Color</span>
- <span size="32">Font size</span>
- <span style="serif">Font style</span>

Finally, you can force newlines with the 'br' tag:
Line 1<br>Line 2
