Corrected spelling on PrefChoiseSelector name, will get the translation keys some other time.
Added LineMetrics.descent to the line height for laying out the text in RocketInfo.
1. Mass tooltip only displays totals for components that have children.
2. setMassComponentType now fires NON_FUNCTIONAL change event.
3. Label now reads "Mass Type" and default is "Unspecified".
This patch is based off a thread from "The Rocketry Forum"
( http://www.rocketryforum.com/showthread.php?70475-Problems-with-custom-motors-in-OpenRocket ) .
Complaint: Poster had a water-rocket engine file which would raise IOExceptions upon automatic load.
(1) the original .rse motor file, posted in the thread above, has an invalid motor length.
(2) The corrected .rse file follows at the end of this commit message.
Bug: The mass auto-scaling code would over-estimate the mass loss, and declare a negative mass upon motor exhaustion.
The negative mass is small (in this case, ~= -1E-16). However, this error is larger than the single-precision epsilon.
Fix: Added a loop which checked for negative mass during the thrust curve, and reset those values back to zero. (AbstractMotorLoader.java:105)
Also, expanded the number and detail level of some related exception reporting. (ThrustCurveMotor:137)

computeTumbleDrag() is never called without this fix.
The one-arg constructor is the only constructor ever used, to init this
status based on the previous status, copying the tumble drag if it can.
The first BasicTumbleStatus is constructed from an RK4 Status, so it's
drag is not copied, but neither is the drag computed. From then on the 0
is copied from one BasicTumbleStatus to the next.
Added functionality to the RocketComponentVisitor by providing a
templated return value.
Modified the Configuration tab UI to disable recovery & staging tabs
when they are not appropriate and adding some help text to the motor
table when there are no motor mounts defined.
