restart link if this occurs more than 3 times

added linear alpha to dispersion plot

added timeout on reading status line

added temp reading in .out file

Now keep reading lines until status length is >= 27
### No track_phase: attempt: 1
No longer wait for three sfp ena attemps but immediately restart the link.

switched to wrpc-v4.1 and wrpc-sw master branch with Adam Wujeks "long fiber, huge pps offset" bug fix

Selectable via a constant, wr_serial is made universal for masters being either a switch or being a SPEC / CLB.

Modified wr_serial to acces the switch and restart the links via USB2 (hardcoded for the time being) using the command:
/etc/init.d/hald.sh restart
