[FIXED JENKINS-9807] : [Maven Jobs] Post build deploy task : Deploy with unique versions (timestamp) should be configured by default

Dependency

Replace crappy VersionNumber with better implementation.

replace old CDDL+GPLv2 Version Number comparator with one that is both ASL and has a better understanding of Maven version numbers (with some tweaks for wildcard support)

o Had to change the logic of two test cases (2.0 is now newer than 2.0.ea and 1.12-SNAPSHOT is no longer equal to 1.11.*) both of which make more sense than the original test cases

o Should now allow custom builds with text/alpha qualifiers in the version number.

miserably.

Fix whitespace in maven installation

ViewGroups like NestedView to override)

I think we use the word 'description' elsewhere inside Jenkins to refer to human-readable text (like job description), so I'm making description the localized string. I'm assuming Kutzi has some use for all upper-case ID, yet the notion of 'upper case' only makes sense in some locale (for example not in Chinese), so I'm now calling it ID and I'm deriving it from the English localization.

moved to the model package to colocate with the Result class, since I don't think this class is tied by itself to the notification.

This creates incorrect links in output from the svn-tag plugin.
