cNssm Key based solely on ExeFolder

[Shwaunk]

Currently the key for the cNssm resource is based solely on the ExeFolder. I feel like a better logic for this is to have ExeFolder, ServiceName and ExeOrBatName all have the key qualifier -- otherwise executables in the same folder cannot be added with two resources or the same executable cannot be added twice as services with different names as two resources.

I have a fix for this but do not have permissions to push my branch and cut a PR.
