Crew Retraining

The big change in this release is the ability to re-train crew. Move the Kerbal that is going to change careers into any research lab (yeah, you have to kick out the scientists) and click on the 'Crew Training' button in the tweakables menu. This release also takes halting steps towards integration with the "Contract Configurator" mod. If you have reached level-3 farming, you may see rescue contracts appear where you'll be required to find the kerbal and bring them back to your base at which point they join the crew.

It also fixes a longstanding bug with resource transfer where vessels that had multiple stages would be unable to transfer some of their resources.

Also, truly keen eyed observers who have installed "Contract Configurator" may observe that I have fixed a longstanding deficiency with the loading blurbs: I have added "Calculating Victor's vector..." to the list.
