--Drove rover on one loop (counterclockwise) of EE313 complex and one run out EE313G, left down to water fountain, and back into EE313G to give Dan some live log files with IMU and encoder data to use with Kalman filter.
--Built run-sensors.{cpp,h}, which will run the encoders and IMU in sync with each other.  Basically it's a merge of run-encoders and run-imu.
--Modified rover_server_log() in toollib-rover-cpp.cpp to use only two connections to imu-log.txt (since encoders and IMU are now together).  Seems to work well--combined IMU & encoder messages are on a single line, and the GPS messages are interspersed.
