[FIXED JENKINS-18013] Make "Project Name" to be a hyperlink
Added repositories to pom.xml
Fixed a test
Need 1.420+ parent POM to even build on Java 7 (e.g. on BuildHive).
require 1.475+

1.475+ is required so we can use AbstractProject.supportsMakeDisabled to check if a row should have a "disable" button
check supportsMakeDisabled before creating disable button

job that don't support doDisable, or TopLevelItems that aren't AbstratcProject (Folders for sample) should not get a disable button that has no effect
Use absolute URL to enable/disable action
