issue with get_all_web_service_custom_policies()

Nobody has claimed this yet.

I can connect with MxConnection and get a version number back (its how I verify its working)
but when I attempt to iterate over the custom web server policies it crashes:

MX version 14.6.0.30

Traceback (most recent call last):
File "policiesSync.py", line 17, in
for pol_c in mx_cloud.get_all_web_service_custom_policies():

imperva_sdk.core.MxException: Invalid string value for parameter - 'Name - WPS Hide Login Plugin Bypass #1'

I checked by the web gui and WPS Hide Login Plugin Bypass #1 is an actual policy name, so I can see its doing something.

Start with WebServiceCustomPolicy.py at _get_all_web_service_custom_policies and _get_web_service_custom_policy, following the call from MxConnection.py. Inspect core.py's validate_string using the reported policy name, then reproduce get_all_web_service_custom_policies(); done means valid custom policy names can be iterated without the shown exception.
