Fix hanging bug and improve time line display.
In this merger request I have changed:
- The command parameter box can be edited and synchronized between the two windows.
- Remove the two redundant "0" corresponding to the tasks with no transaction on FPGA.
- Remove the "HW" title.
- Make time indices are more closer with transactions.
- Fix hanging simulation by adding condition for the termination of simulation.
- Add a new test for checking the simulation is terminated or not.
