Update resume for 2013.

* Change theme to work with the moderncv package I have installed on my
  new machine.
* Update homepage to my github account.
* Change and comment out the objective. The original was too sappy.
* Update skills.
    Get rid of things I haven't used in a while. I haven't worked with
      Objective-C or PowerShell in forever. Nor do I expect to work with
      C++ in the near future. (never say never though)
    Comment out sections that are meaningless. Do Operating Systems and
      IDEs matter?
* Add things I've done at Backstop in last few years. I've probably
  forgotten a ton.
  Rewrite some of the items to make it clear how business benefited.
* Fix AgileTek section.
    Add mbox to prevent wrapping.
    Fix spacing in tex file.
* Add few interesting MOOCs I've taken.
* Get rid of activities I did in college and high school. I doubt anyone
  cares anymore about my participation in ICPC or the Web Design Club at
  this point.
* Add a few personal projects I've worked on recently. Primarily open
  source stuff, but also Lending Shak.
* Regenerate pdf from new tex source.
