[JENKINS-22388] Possible to move cppcheck summary into main job hudson page?

- Project action updated to be standard Action instead of ProminentProjectAction.
- Icon from project action is now displayed only in the main menu on the left so correct 24px icon is used instead of 48px one. The larger icon was required by ProminentProjectAction that was rendered on top of the main page.
- Project action is now able to provide last build action. It is used in new jobMain.jelly that renders the statistics in the project action page.
- Build action summary uses urlName and displayName instead of the hardcoded strings.
