Call GetConnectedResources with the resource's flow mode.

0.24.1 added the extra parameter, presumably as a fix for the vernor issue
(I haven't looked that deeply). It seems that it is possible to override a
resource's flow mode, but I chose to keep Kethane's behavior with respect
to LiquidFuel and Oxidizer the same as in earlier versions.
Update CC for KSP 0.24.2
Set version to 0.8.8.1

This is just to distinguish this fixed Kethane from Majiir's official
versions.
