Implementations of DirectoryBase should throw DirectoryNotFoundExceptions when path arguments correspond to unmocked directories.  This mimics the behavior of System.IO.Directory, as described in http://msdn.microsoft.com/library/07wt70x2(v=vs.110).aspx.
Add unit tests for throwing DirectoryNotFoundExceptions.
Code style cleanup
Added base and wrapper for the FileSystemWatcher class

Removed jmconfig file (no idea where that came from)

Updated Base and wrapper classes to properly deal with the events and bubble up the concrete FileSystemWatcher events up to the wrapper class.
Merge pull request #59 from KallDrexx/FileSystemWatcher-Abstraction

Added base and wrapper for the FileSystemWatcher class
Created FileSystemWatcherFactory class to to make it easier to test code that needs to generate file system watchers
Added code and test to create the mocked directory when called MockFileSystem.AddDirectory()
Updated all FileSystemWatcher events to be virtual, to make them possible to raise via mocks.
