Top Level Try-Catch and Client File Name

Added a top level try-catch which should prevent the application from major crashes mid-run. Still need to add logging or something to dump the caught errors into. Also made the application resilient to renames and potentially running from different directories, etc.

Initial Working Version

This is the first functional version of cpss.

It was written in about a day so there are bugs, bad code, and maybe some low-security means to our humble end, but it will open remote powershell sessions with many computers provided those computers all have the same username/password.

We'll work on getting a more robust distributable than a binary next time. The binary was tested on Windows 7 and requires .NET 4.5.
