Subject: Mantis#1591. Thank you graciously, Sempuki for a patch that:
 Currently module loading is done ad-hoc. I propose creating a simple loader
 class that leverages Mono.Addins (and perhaps the new .NET addins when they
 become available in mono). Attached is a basic patch for review that compiles
 into HEAD, but doesn't yet replace any existing ad-hoc loaders.
