styling of static pages

This fixes #95. I went with a 3-column layout for the FAQ and pricing pages as the original 1160px were too wide for any pair of eyeballs to easily keep track of the active line. Did the same for the jobs page, but using 2 columns instead of 3.

I added the missing breadcrumb in faq.html, and fixed the un-encoded `&` in jobs.html, but other than that the HTML semantic structure remains pretty much the same (expect for the fees.html that now uses `dl`, `dt` and `dd` tags).

Since these are very specific styles, I've added all the custom CSS in-page (using the block level `style` tag).

Here's how it looks:
