Added ability to remove nssm parameters
Added ability to remove nssm parameters

You can now remove previously set nssm parameters by setting the hash
values to '' for Strings, & 0 for Integers. Also improved how the
Consul service is stopped on Windows. If you don't stop it before
you remove it, you end up in a SERVICE_PAUSED state.
