CIM_ComputerSystem created from WMI should have lowercase host name

CIM_ComputerSystem created from WMI should have lowercase host name.
When going from the WMI page (entity_wmi.py) to the related survol link, it uses a host name in uppercase, although they must be in lowercase.
The consequence is that a wrong URL is created (host name in uppercase) but the alias is OK.

Example:
http://rchateau-hp:8000/survol/entity.py?xid=CIM_ComputerSystem.Name=rchateau-HP

This URL also creates the node:
http://rchateau-hp:8000/survol/entity.py?xid=CIM_ComputerSystem.Name=rchateau-hp

These two nodes are linked with an read "Alias" edge.

But this is not correct, because the hostname should be converted to lowercase.

I tried to use in CIM_ComputerSystem:init.py the same technique as query/init.py by replacing an string in the ontology by a derived class from str: This t(echnique allows to transparently encode/decode property values.

This does not work. See class CgiPropertyB64.
