Updated Version of MyNotes

MyNotes 2012 is an updated/re-worked version of the MyNotes sample that
goes in a slightly different direction.  Rather than have two
databases--one for the event store and one for the read model--MyNotes
2012 focuses on having a single database, but with the possibility for
separate schemas.  MyNotes 2012 also updates the technology stack
slightly--eliminating edmx files in the read model in favor of POCOs,
using MVC4 for the web UI, and setting the root namespace for all the
assembly projects to "MyNotes".
Changed HintPath of library references pointing at the "packages" folder.
Changed Primary Key Names

Updated the script so that the primary key names reflect the tables they
belong to.
