Add a Windows Service host as an alternative to the GUI


Proposed by http://www.codeplex.com/site/users/view/ReneHezser

Originally, ServiceMon only provided feedback of monitored systems using its display. With the introduction of the #email-summary and #email-on-threshold-change directives, it is now feasible to run ServiceMon in the background, with nothing shown to the user.

A Windows Service would be an excellent alternative method to the GUI of hosting the ServiceMon monitoring engine. This would enable ServiceMon to run without needing to have a user logged-in to Windows.
