XML Import-Export incorrect handling of Host group names

When exporting templates with an & in the Host Group name, eg "Network & Comms", the exporter is stripping from the & onwards. I.e. this is the resultant line in the XML file:
<group>Network </group>

This creates a significant issue when re-importing as a new Host Group is created with the wrong name and the imported items in it, instead of importing into the correctly named Host Group.
