Added Nebraska scraper

Initial work by @rnelson and @dlipskey
add alabama itbs config
add alabama itbs scraper
change directory structure, start scraper refactor
the goal being to have one scraper do ITBs and RFPs instead of having two
separate scrapers
add zombie dependency to package.json
boilerplate and placeholders for headless crawl
fill out more of the headless crawl
using promises instead of callbacks because brain hurts
the first page is working fine, need to paginate
looks like there's something weird going on with zombie's .clickLink
method - it's throwing errors when i use the link text instead of a
selector, which it shouldn't be doing according to the documentation.
tests pasing, getting ITBs and RFPs
named it solicitations.coffee since it contains ITBs and RFPs both
add RFP site to yaml
yaml now has sites for RFPs and ITBs
doh! use the right yaml syntax
Fixed the NE scraper as of 2014-03-17

CSS style on some table cells changed, which broke the parser. That
particular issue is now fixed as we're looking for the nth child <td>
instead of the nth child node with .cell-purch.
config.yml: enclose urls in quotes
solicitations.coffee -> rfps.coffee
add html_url to RFPs where property exists
simplify conditional
