Changes:
- Remove floating versions
- Disable myget feeds during a Universe build
- Use package-specific MSBuild variables. Pattern = `packageId.Pascalize() + "PackageVersion"`, with a few exceptions.
This is an improved implementation of the ActionSelector for conventional
routing. This will do fewer dictionary lookups than the decision tree, and
will avoid OrdinalIgnoreCase hashing in the common case.
