Existing MovingTime references changed to TimerTime, added a real MovingTime stat, everything makes much more sense now. Updated handling of RK's "duration." Enabled all services to synchronize stationary activities with waypoints but no GPS data. Rewrote ST.mobi waypoint download code to support this. Switched a few int()s to round()s. Worked around a Strava bug that that presents timer time as moving time in cycling activities.
