An annotated string handler that allows handles annotations that begin with
{@link #SUPPORTED_ANNOTATIONS}.  This class expects one or two strings following the annotation.
The first string will be treated as a Java {@link URL} and the optional second string will
be treated as display text.  If there is not display text, then the URL will be
displayed.
