[Article 612]Send SMS from Powershell through Unwire

At work we have bought an SMS gateway service through the danish company Unwire, so after we the deal was signed we got the information on how to send email through their services, so in order to test I wrote a quick Powershell script to test it.

Of course all company/Unwire specific data has been removed, since it relates to our company account.
