Introduced AbstractProject.supportsMakeDisabled rather than using trick of checking for parent instanceof Jenkins.
Extracted common GUI into makeDisabled.jelly, with accompanying I18N refactoring.
Also moved all this into AbstractProject, where the relevant methods are defined, rather than Job where they are not.

One of the problems with the current way Jenkins puts JavaScripts is that most everything is in a single file. It doesn't highlight the relationship between those fragments and their corresponding tag files.

So I'm experimenting with moving out these fragments into individual JavaScript files co-located with the tag file. They then get loaded into the page via <st:adjunct>. Each script is served with unique URL such that the browser will not even have to try conditional GET when loading different pages, so this should prevent the performance problem caused by the fact that there are now lots of <script> tags in the page.

 If for some reason even this turns out to be a problem, we can always add additional build steps to concatenate them all.

reapplied the correct fix.
