Change part name underscores to dots

KSP changes underscores to dots in part names, so the default cfg is wrong because it has underscores.
This causes Kerbal+Part recovery contracts to break because the part name does not exist.

Good find; had just ran into those last night and was wondering what the cause was.

Will fix that up ASAP and post an updated release.
