Edited Task: [NonVS] Update Power Tools to work with EF6 [1165]

We were going to consolidate the Power Tools/EF Designer in EF6 but were not able to do this. In light of this we need to update the power tools for EF6 by the time it RTMs.

EF6 also has a new API for performing view generation. We need to update the Power Tools to handle this.
