Missing code in thml.ATag causes missing osisRef attribute in reference

I believe there is some missing code in thml.ATag. In StrongsRealGreek there are references like:

<a href="sword://StrongsRealGreek/01909">1909</a>

and the above is currently converted to OSIS as:

<reference>1909</reference>

However I think it should be:

<reference osisRef="sword://StrongsRealGreek/01909">1909</reference>

Joe has left the following comment in ATag which seems to confirm that some code is missing:

// LATER(joe): put the correct reference here

I added the following just before Joe's comment which seems to fix the problem:

String href = attrs.getValue("href");
if (href!=null && !href.isEmpty())

{ reference.setAttribute(OSISUtil.OSIS_ATTR_REF, href); }

I will attach the amended ATag.java and also a junit test. If nobody comments adversely before next week then I can check in the junit and fixed code next week.

There is probably also an issue with xml like "<a name="01993">1993</a>" which is not addressed by the attached fix.
