some changes with the jumbotron class

just made some tweaks to the css
made some structural changes to the layout

fixed the layout and now I’m in compliance with Bootstrap.  this will
help me out later and should prevent me from screwing it up later.
number of changes, added work section and fixed some good text

This change wasn’t that great; just fixed some css, added some real
text, and added a work section.  That section won’t be very great, but
at least I’ll be able to show off some things that I’ve done.

After that, I’m going to try and finish up some of these outstanding
apps that I’ve been “working on”.
