Easy one: Convert this to a VS2015 project

Also set the default runtime to .NET 4.5 so that we don't have compat issues with the parent Halcyon project

Since time has moved on, just confirming you want it set to 4.5 instead of the current 4.5.2 or 4.6?

[ddaeschler]

We cant change away from 4.5 without requiring every other project to also be updated, so for now this needs to be 4.5

Committed reversion to PR that set it to 4.5. Note that before the PR it was 4.5.2.
