It corrects a segmentation fault added for my previous patch :-/

If you openend atlantik and closed it, it segfaulted, because m_job was not 
initialized to NULL.

I've also added a timer, if the connection doesn't makes signals of life 
(slotData) in less than 10 seconds the job is cancelled as i think it is 
pretty safe to think that the connection is having problems.

Along with this, now when you click on "Refresh server list " the button 
becomes not enabled, because previously you could click hundred of times and 
it started a hundred of m_job

What do you think of it?
