Title: JENKINS-14325: CCE & missing GUI when using jobs inside folders

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.
