Change version number for public release

Andreas Gottwald sent a patch which fixes an issue, when the CIM element was a "NoneType" element but the plugin wanted to read a string from it. 

    Traceback (most recent call last):
     File "./check_esxi_hardware.py", line 629, in <module>
    verboseoutput("  Element Name = "+elementName)
    TypeError: cannot concatenate 'str' and 'NoneType' objects
