Some fixes and enhancements

date Version = 20130421
This build corrects some bugs I introduced in the 4.0.1 build in my
eagerness to get certain new features out ...this has been fixed and I
have gone over a new procedure of testing EVERYTHING (each procedure)
before releasing a development build.
One major accomplishment was retooling the XMLRPC plugin service for
better/deeper  integration with Zenphoto and fixed a long time problem
with the image sync logic ..
It now versify's both the filename and the date of the capture that is
embedded in the EXIF data. This "will" end the issue where the default
filenames such as IMG_001 in another folder in you lightroom library
some where will not be used unless the date matches .
(This has been  big problem for me personally)
Other small enhancements and corrections (more debug code too)
