Allow setting random seed as parameter
Make regressiontest reproducable
Clean up setting channel and CCA-threshold for CC2420 based motes.
The CCA-threshold now defaults to -46 which give better simulation
results and typically also better experimental results.
This adjustment is also needed due to commit 0a13f99 in mspsim. As
promised in https://github.com/mspsim/mspsim/pull/18 it broke the
regression tests.
Added mspsim as a submodule instead of as a binary mspsim.jar file
Tolerate loosing one packet in  01-sky-shell-collect.csc
Remove broken test from regression testing
Move simulation execution from Makefile to Bash script; show Progress
Additional code is needed to show the progress. Otherwise Travis is
likely to become unhappy and terminates the job. This was no fun within
the Makefile. Moving the execution to a Bash script allows better
maintainability.
In case of an error the error all logs will be printed when using a CI.
Merge pull request #407 from cmorty/submodule

Add submodule support for MSPSim and get Travis green again.
