PLCOnNet development state

This release comes with some ready made classes:

• PLCOnNet:
  • Reflected almost all classes of PLC4J with the limits imposed from JNetReflector
  • Manually made some classes, or extended some of reflected one, due to limitations of JNetReflector
  • If something is not available use API extensibility to cover missing classes.
• PLCOnNetCLI: added REPL shell, run Main-Class and execute C# scripts
• PLCOnNetPS: some PowerShell cmdlets
