Added couple of simple unit tests for computing area and cg for
Trapezoidal and Free Form FinSets.
Merged changes fixing NaN when computing fin CG.
If the user selected a really small (0) timestep, the simulation gets
into an infinite loop.  Don't use a user selected timestep smaller than
MIN_TIME_STEP.
Ignore simulation time steps <= 0 when loading ork file.
Break up the area/cg test cases and add some documentation describing
what they are doing.
Cleaned up imports.

Bugfixes 1
Try to use Java Serializable to improve loading of included
ComponentPresets.
Remove bin/ folders from reposiroty
Guice module for loading plugins
Startup system using Guice and plugin loading
Remove test jar
Make ClassBasedTranslator compatible with Guice
Refactor the EditMotorConfigurationDialog into its own package
"flightconfiguration" and pull the TableModels into their own files. 
Changed layout so all the buttons are on the bottom.  Made the
configuration name editable in the table itself.
Made the config selector a combo box with buttons to control add, rename
and remove.
Added more buttons to configuration including broken copy button.  Added
tab layout to pane.  Added ignition spec to motor config table but
haven't hooked it up.
Added some l10n strings to the motor table.  Tightened up access to
package scope member variables.
Implemented a DeploymentConfiguration object which includes the values
used to determine the deployment of a recovery device.  The DeployEvent
enum was moved into this class.  Added a map of configuration id strings
to DeploymentConfiguration objects in the RecoveryDevice.  Modified
various setter/getters in RecoveryDevice to support a "default"
configuration defined in the device's configuration dialog.  Modified
BasicSimulationEngine to use the DeploymentConfiguration based on the
selected configuration.

Added to the FlightConfiguration dialogs to support editing these
configuration.

Missing are serialization of the map in ork files.
Wired in remove deployment configuration.
Pulled the setup of the Motor Configuration panel out of
FlightConfigurationDialog in to its own class.
