MUMUP-1138 : Add in ability to generate update scripts
[NEWSPLT-96, UP-3846]  Add styling fix for disabled pager buttons.
[UP-4060]  Show the configure screen in a lightbox instead of displaying it inline.
[UP-4060]  Fix to remove unnecessary "done" callback that was accidentally in a "then" anyhow.
[UP-4060]  JSDoc fixes.
[UP-4060]  Remove config-in-lightbox support from portlets in the content area.
[UP-4282] Convert legal footer to a simple content portlet instead of JSP so that it is easier to edit.  Make the footer-second section a bit more of a real region.
I also removed a bit of the styling to reduce some of the portlet specific styling in the portal.  It can't all be removed, but a large chunk has been removed.
[UP-4275] Add documentation to help distinguish between name/title.  Fixed title in site map link so it is consistent.   Add tooltip to the customize gallery to display 'name' and 'fname'.
[UP-4282] Convert back to using relative sized fonts for content (kept hover to fixed size to match size of hover option elsewhere)
[UP-4282] Remove old JSP.
Formatting: remove extraneous newlines.

Rely on reasonable text editors to wrap paragraphs to the editor window.  GitHub's web-based editor does this.
Emphasize contributor license agreement.
Add advice re communicating.
Trivial: fix typo: "committing" --> "committing".
Add advice about coding and collaborating.
Pull requests and JIRA as communication opportunities.
Further justify having a JIRA issue for the change.
Trivial: fix typo "inclusing" --> "including".
Standardize on JIRA rather than Jira.
Trivial: blank lines after section headings.
