Edited Task: EFTools: Add EF6 App/Web.config IntelliSense (xsd) [1014]

The App.config/Web.config IntelliSense files that get installed by EFTools.msi should be updated to include valid EF6 elements.

The xsd for "validating" EF config section in web/app.config file does not recognize newly added EF6 elements. It should be updated so that it does not show squiggles for valid EF6 config file.
