[etherlab-users] master startup script uses bashisms

[martin troxler]

the ethercat startup script /etc/init.d/ethercat uses the 'function'
keyword which is a feature supported only by the bash.


Since Ubuntu uses the dash as default shell (to improve the boot
process, see https://wiki.ubuntu.com/DashAsBinSh) I suggest to either 
- remove the 'function' keyword
or
- mark the script as a bash script (#/bin/bash)


Best regards
