Workaround for illegal bean properties in XML Configuration

As per discussion on mailing list.
<java.text.SimpleDateFormat>
<lenient>false</lenient>
<2DigitYearStart>date</2DigitYearStart>
</java.text.SimpleDateFormat>

Won't parse due to the '2' at the beginning of 2DigitYearStart.

I added a 'map-to' property in org.nanocontainer.script.xml.BeanComponentInstanceFactory that when present allows for such mapping. So the following would be applicable:

<java.text.SimpleDateFormat>
<lenient>false</lenient>
<yearStart map-to='2DigitYearStart'>date</yearStart>
</java.text.SimpleDateFormat>

HTH!
