Resolved issue #496: Updated CommonServiceLocator

Updated the Autofac.Extras.CommonServiceLocator assembly to reference
the latest CommonServiceLocator, which is now portable. Removed
references to the old separate portable CSL. Updated A.E.CSL version for
next release.
Updated dev doc to VS2013
Fixed build so SecAnnotate works again.

Turns out we have to analyze the .NET 4 and .NET 4.5 stuff separately
due to the target framework.
Ignoring TransparencyAnnotationsShouldNotConflict

Fixed a SecAnnotate issue where one particular rule conflicts with FxCop
recommendations. After some research, FxCop is the one we should listen
to on this.
