Bug fix.  Did not set up test of whether ellipticity was in the fields specification.
Additional bug fixes including spelling error on ellipticity.

Fixed bug in creation of HTML file where header was not written properly.
Removed ImageListHeader.html file as it is now coded in to IQMon.py.
Added code which prevents SExtractor background size from being less than 5 pix.  Added code to optionall include target name and exposure time in HTML table.
