Update to VS2012 + Major renaming

Having the 4.0 versioning indicator in the namespace was a source of
confusion. The main namespace is now Simple.Data.Mysql and the testing
namespace is Simple.Data.Mysql.Test
Ignoring another user settings file
Fixed missing stuff after major renaming

Build script and nuget scritps are working
Fixed missing reference to main project from test project
Merge branch 'to2102'
