Bug #23: Change [options] flag to allow repatable options.  Created a wrapper for options on the GsyncOptions class to ensure they can still be compared as strings but with the added provision of being able to access them as a list through python's __getitem__ accessor method.  This now allows repeatble options to be isolated as repeatable without requiring any additional code changes anywhere else (in theory).
Disable httplib debug since it outputs POST and GET requests that could
contain sensitive information.
Fix  bug #27: Incorrect property being referenced for modifiedDate.
Fix bug #28: Reworked options parsing to ensure options are repeatable.
Required some changes to the options module to provide a list accessor
method to the options that can contain multiple values.  Otherwise, the
options class now just returns the last item in the list, using the last
option set - wins approach.
