ENH: Compare messages on github automatically generated when Slicer extensions were automatically updated was not always containing a correct link. This happened when the extension description file was specifying "git://github.com" instead of "http://www.github.com". UpdateSlicerExtensions.script has been updated to work in both cases now.
ENH: CompileSlicer.script takes more arguments and the "how to" help line explicitly states the arguments that are necessary to run this script.
