#45 implemented SQL compact repository and tests
#45 Can now select SQL compact or MongoDB during install wizard. This in turn sets 'DatabaseSystemName' app setting in web.config. Ninject bindings for repositories honour the 'DatabaseSystemName' setting. InstallationController (WebApi) now handles SqlCompact or Mongo when checking for connectivity etc.
