Removing runtime reflection from StilettoContainerAdapter

Replacing the MakeGenericMethod thing with hard-coded type comparisons.  Resolvable types are hard-coded anyways in the same file, so there's no need to be so general (and slow).
Renamed IfFastInjector to IfInjector and nuget-ize integration.
