Namespace gem modules/classes

There is a conflict with gem albacore due to usage of Configuration constant in global namespace by both gems. Albacore declares Configuration as module and inetmgr declares it as class which leads to conflict between them.
Suggestion is to move all classes inside modules which is usual convention for gems. See https://github.com/rspec/rspec-core/blob/master/lib/rspec/core/project_initializer.rb for example. 
To not break existing clients IisConfiguration aliased to global namespace.
