Adding scripts for using Jenkins on a community build server.
Merge pull request #1 from ragerdl/master

Adding scripts for using Jenkins on a community build server.  These scripts will likely be different than the scripts Centaur uses (well, maybe Jared is willing to help me figure out why aliases for startjob don't work inside my jenkins, which would allow us to unify them).
Added .gitignore files, at top level and for books/.

These were taken from svn repo files
unversioned-files.txt
and
books/unversioned-files.txt
respectively.
