Tags for Simulation runs and History button

[anuragmohapatra90]

• The simulation runs are currently tagged with a dd/mm/yy hh:mm:ss format. This is ok but a simple text tag to describe the run would be more useful. Students can then tag a result with its particular property. It is difficult after about 5 simulation runs to remember which was which.

• Also a History button would be useful, to not overload the dropdown menu on the simulation tab. That drop-down could list maybe the last 10 runs and a dedicated History tab for all the other runs.
