Max of host name should increase 128 for the following reasons.

• Virtual machine name can be duplicated, so I change "Name" of "Host prototypes of Discover VMware VMs" to " {#VM.NAME}

  -

  {#VM.UUID}

  "

• Virtual machine name limits is 80.

• UUID character length is 36.

Attached is my patch.
