Fixes #441 and also #442

very small changes that do both bug fixes.
Every time there's an update to KSP itself and I have to delete the old references to the KSP API and the UnityEngine DLL's and add references to the new ones, it has the weird side effect of also making NuGet forget these helpers as well and I have to re-get them.  That's where these changes in the diff end up coming from.
