0.4.1: Fix Fixes

- Fixed the inability to fix the Altimeter and the Thrust Gauge.
- Fixed the Alternator fix action saying "Fix Altimeter" instead of "Fix
Alternator".
- Fixed being able to perform additional actions on a spent decoupler.
- Changed Maintenance context action to read "Maintain <Module>" instead
of the generic "Perform Maintenance".
- Changed the ship color map such that a part with a failed module will
always appear red, regardless of the average reliability.
