Proteus.Utility.UnitTest updated to support new NDbUnit v1.3 build

Now that I have updated the NDbUnit library to support SQLite and SQLCE database targets, I have also just updated the Proteus UnitTest Utility library to offer support for these DB types in its wrapper around NDbUnit.

The new (latest) release is available from the Google Code Site or as a binary download or as source code, your choice.
