Indigo devel - experiment playback for the web console

Hi,
here comes the playback functionality for the web interface. Additionally to the slider you will find a play and stop button to periodically execute time dependent queries. The slider will move with the playback and can still be used to jump around in the experiment.
The queries are hard coded in control.js and may need some editing for the new log file format. By now they display the robot at the actual time and a statistic of all errors until that timepoint.
Best regards
Arne
