Moving files that should all be reusable through TriBITS

We will change the names of the files and generalize their contents later to
remove all 'trilinos' references.
Changed name of file to be more descriptive of contents.
Allowing CDash package regression email addresses to be specialized at the project and repo level (bug 5580)

The existing behavior for default Trilinos regression email lists has been
maintained but now the regression email list for a package can be defined at
the project level or the repository level.

This will be used to better specialize how meta projects like CASL VERA define
their CDash regression emails.

Other things done:

(*) Removing unused 'checkin' email list from xml files.  This email list was
never used and never should have been put in.  If we need to associate more
email lists with a package we can add support as needed.
Added ability to not implicitly enable packages from a given repo with exception list (VRI Kanban #2529)

This will be used to exclude most of the SCALE packages from VERA testing.
Merge branch 'master' of software.sandia.gov:/space/git/Trilinos
Adding some documentation on adjusting CDash regression email addresses for TriBITS packages.

There is stuff being documented here that I did not know until just a few
minutes ago.  This is important stuff if you are maintaining a TriBITS project
and using CDash.
Adding an example of using DocUtils for the TribitsUserQuickstart.txt

Here I just took part of TrilinosCMakeQuickstart.txt and tried using DocUtils
and reStructuredText to see how the the formatting works.

I generated the *.html file with

  $ rst2html.py TribitsUserQuickstart.txt TribitsUserQuickstart.html

I generated the *.pdf file with:

  rst2latex.py TribitsUserQuickstart.txt TribitsUserQuickstart.tex

followed by:

  pdflatex TribitsUserQuickstart.txt

This file will be completely replaced by an updated version based on the most
recent copy of TrilinosCMakeQuickstart.txt.
Fixing small formatting issue
Adding skeleton for sphinx project files for TribitsUserQuickstart.rst
Adding just the basic generated files for TribitsUserQuickstart.rst with sphinx

I left out the rest of the generated html-related files.  I just want to put
this in to the git repo as an example to show others.
Fixing PDF input source.
Merge branch 'master' of pu239:/home/8vt/PROJECTS/Trilinos.base/Trilinos
