Updated README.md with instructions 

of where to find and/or create PRODUCT_ID and API_KEY on Xively.com
first pass at #48 ("Need to be able to see all 900+ eggs")

My initial approach is to a) move the fetching of feeds out of the root
route and into an JSON AJAX API one and b) add a caching layer. A
slightly better approach might be to load 100 eggs at a time through
javascript (this approach loads all 900+ at a time).
#48 cosmetic changes to make it clear this is not the official website
#48 fix banner CSS, remove cache flush
tweak cache time
#48 refactoring fetching of all feeds into private #fetch_all_feeds and some very basic logging
#48 refactoring, documentation, and formatting; also added endpoint to flush cache
beginning of #37: adding endpoint to retrieve recently added (created)/updated (retrieved)

Choices:
- HTTP GET /recently_created_at.json
- HTTP GET /recently_retrieved_at.json
#48 load map (and therefore hide "looking for eggs" message) after feed is loaded
#37 show JSON on home page - will beautify soon
show # of eggs on web page
#37 show list of last added and updated eggs on site (need to make it more user friendly though)
#37 added moment.js to show humanized dates ('from now')

Remove remaining use of device tag (seems better to search by user not
tag) and also replace URLs with $api_key variable for consistency

Update individual egg pages to use Javascript to load nearby eggs
(after page load) and some other improvements including code comments
and other cleanup
#48 (Github) [#69362528 #69362500] add search box
removed warning header
Merge pull request #5 from WickedDevice/master
