Pass through task-link CSS class to confirmationLink dialog

Add console-output class even while div is in progress

>> cell.innerHTML ;
"<A class=sortheader href="#"> S<SPAN class=sortarrow></SPAN></A>"

Fix jenkins restart on Linux after a JRE system update

Daemon.getCurrentExecutable() use /proc/PID/exe to retrieve the used JRE. This link is broken when the target changes (ie after a JRE system update) because the kernel appends ' (deleted)' to the symlink. This patch uses the first argument of the command line (in /proc/PID/cmdline) instead.
