Remove unnecessary js, update work info

Truly, the worst programmer you've ever met is yourself from six months ago. With the power of hindsight, some basic knowledge of javascript and the slightest bit of taste, it has become obvious that whatever cockamamie scheme I dreamt up before for allowing users to collapse bits of my website was a terrible idea. It has been purged from the land.

Xtreme Labs is sadly no longer Xtreme Labs, and I'm finally getting around to admitting it through my website.
Remove "What I'm Good At"

Selling yourself only goes so far, and that section was absurdly narcissistic. I wasn't even happy with the writing in it.

Correct spelling of "visualization" in DUG info.

Update Pivotal Labs info a bit more. Takes out all references to Xtreme (other than in the title) and more accurately reflects what we're doing as a company.

Expanded on the "tech I like" to mention more than just Java, and throw in an OwnCloud mention too. It's pretty cool, and I do indeed like it.
Convert HTML index to Markdown

Certainly seems much nicer. Considering I'm using this pretty much entirely for words, Markdown makes a lot of sense.
Replace <a href> tags with Markdown links
Merge Who I Am and What I've Done

The two sections were too similar-- the first had too little content, and much of the content in the second was as/more appropriate in the first.
Add images to each employer entry

Each image is clickable (redirects to the company). Gives the page a bit more flavour.

No style for mobile devices, as the degradation seems surprisingly good on smaller screens. Haven't yet tested on an actual mobile device.
Minor wording change
