Added optional parameter 'force' to vos.Client.listdir.  This is passed along
to getNode.  The end effect is that if force is set to True then cached 
results will not be used for the listing.
reloved conflict in version number
Merge pull request #13 from drusk/force_listdir

Added option to avoid caching of results when calling listdir.
made debug logging include line number
use delete to remove lock instead of 'false', this maybe a service bug work around
corrected logic check for success and fail on lock setting
added back the clearProps method as that is used by recursive vchmod.  increased debuging output on http connections. added islocked to the list of bless properties of VOSpace
Pushed version number as locking now works and web service is not defaulted to canfar.phys.uvic.ca
Moved files into a more pythonic order.

The CADC build system uses ant and a build.xml file had be added to
make this python project sort of install correctly for CADC.  But
that's not very generic.  To enable usage of the tasks without install
I've placed the main scripts in the main package dir (again) and
removed the build.xml
set URL to None when shortcut fails, triggers slow road approach
