Ignore changes to ignition, stage separation, and motor configuration.
Fix initialization in constructors so all constructors initialize the
motorConfigurations and ignitionConfiguration.  This fixes unit tests.
Added BaseApplicationAbstractTest base class which will use Guice to
create the application framework.  It is roughly equivalent to the first
step of bootstrapping with ApplicationModule.  Modified unit tests which
require a more complete application framework.
Fixed RocksimDocumentDTOTest by having RocksimTestBase extend
BaseApplicationAbstractTest to create a more complete Application
object.
Allow setAppearance to accept a null Appearance parameter without
throwing NPE.
Merge pull request #64 from kruland2607/master
