Update Vhost.php

Merge pull request #10 from rgrwkmn/master

Added missing description option to takeSnapshot

Fixed bug where a missing index in property retrieval created an infinite loop. This may be a bug in vSphere itself but now it's handled by checking for the existence of the property before trying to access it after retrieval (since it's not there is just starts the process again).

Added getChildren method to Folder so you can get all the children of a certain type from that folder.
