[JENKINS-16184] Also escape greater-than character

[FIXED JENKINS-25074] Make sure to call Job.getBuildHealthReports just once per t:buildHealth render.

Based on the reaction to these issues and JENKINS-24514, I'm partially
reverting the original change, and bringing the umask default back to
022.

The configurable option does enable the user to choose a different
umask, so I think I can still claim that JENKINS-24514 is addressed.

[FIXED JENKINS-24703] Do not set any colors for input elements

This version includes a change from christ66 in
https://github.com/stapler/stapler/pull/40

Turns out there was a security advisory posted on Ant 1.8.3
(http://ant.apache.org/security.html) though the affected code is not
used in Jenkins.

Reference: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2098

Convert AbstractProject to better utilize structure form submission.

For example, the following should not cause Run.onLoad itself to fail:

[FIXED JENKINS-23020 JENKINS-23942] Convert the queue's cancel shutdown to POST

Both 0 and 1 are used to indicate some kind of success (the latter when Jenkins doesn't need to be started because it was already running), so we need to return 2.
