Taught MassFlow and SpecImpulse to play nicely.
Added several craft-relevant derived properties.
Added a generic "setValue" method, which is currently unused.
Rounded off the number values to 6 sigfigs.
Part.__init__ will now correctly parse parts within .craft files.
Added globally-accessible configuration values.
