[Pharo-project] [Jenkins] 1.4 jenkins setup improved

Some progress on Jenkins: -> image and all zips are now names Pharo-1.4 (not Core) -> there is now a one-click image (build using same script /vm as 1.3) -> image is saved to image directory as "Pharo-1.4" for other jobs to build on top. https://ci.lille.inria.fr/pharo/job/Pharo%201.4/ -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.
