bug described here: https://nexedi.erp5.net/bug_module/20140718-1A93B96
runner: javascript global var is now declared in a local scope
runner: /viewLog now displays the date of last build and run
runner: /viewLog displays "Queue" for Run only if the run_instance option of slapgrid is set to true
runner: correctly displays the "run log" after the build step, even if the slapgrid process is very short in time
runner: quick fix to a bug in UI, during slapgrid run.

This bug makes the display of "Running instance..." 2 times instead of one
