A job can crash if its name is too long

[Michele Peresano]

Not clear at the moment what is the maximum allowed length.

An easy solution would be to add an option to change the prefix of a job's name.
The prefix should be defined as everything before the analysis step, so "prototopipe_" and analysis name.
The rest of the job name shows analysis step, particle type, and run numbers which are information necessary for debugging.

The cleaning mode suffix could be already removed permanently as it's useless anyway.
