Updated Crescendo to 0.4.1

[theJasonHelmick]

We had a small bug in 0.4.0 that may generate proxy cmdlets with the ternary operator, preventing the module form working down level to Windows Powershell 5.1. We released Crescendo 0.4.1 to remove the generation of the ternary operator in the proxy module. The blog is updated and Powershell Gallery now has Crescendo 0.4.1. The output handler in the IPConfig example was also updated to remove the ternary operator to support Windows PowerShell 5.1.
