Jenkins LTS based official image

As discussed with Brian Goff - here is the official Jenkins repo for inclusion. 

Jenkins has a weekly non long-term-support release schedule - but we thought for the purposes of stackbrew we should stick to the LTS versions of Jenkins - which are infrequent enough that a pull request is feasible. 

For a logo, here is the official one in png form: https://camo.githubusercontent.com/73aa2e5efdce9c86a20922bc04f9c2bde852be4f/687474703a2f2f6a656e6b696e732d63692e6f72672f73697465732f64656661756c742f66696c65732f6a656e6b696e735f6c6f676f2e706e67 
So, I'm not very familiar with how Jenkins versioning goes, but is it reasonable for Jenkins users to also say, for example, that they just want "jenkins:1" or "jenkins:1.554" to specify that they just want the latest "v1" or the latest minor version of the "v1.554" release track?

See https://github.com/dotcloud/stackbrew/blob/master/library/python for an example of a separate image where it does make sense to do this, for reference.

Note that I'm not saying you necessarily have to do this for me to sign off here, but I want to make sure the question has been asked, in case it does make sense to do so. :)
