Renamed Glimpse.Core.Configuration.GlimpseSection to Glimpse.Core.Configuration.Section
Moved RuntimePolicy.cs from Glimpse.Core to Glimpse.Core.Extensibility
Fixed a bug I found inspecting the Configure code of all implementations of IConfigurable
Documented all of the Glimpse.Core.Configuration namespace for issue #230.
Added [Sandcastle Help File Builder](http://shfb.codeplex.com/) project file and installer. Also added a `psake docs` build target to create the documentation file for issue #230.
