Added new relic tracking

* Updated chnagelog
* Added snipetting demo to /why page
Remove and ingore newrelic logs
Hopefully, fixed ElasticSearch

After some investigation, it turned out ES has only 9mb of data and
yet is running at 100% CPU & RAM. I think this was coused by
"offsets" having type object... since "offsets" was different from
document to document, ES had to re-dynamic_map every document, on each
insertion. "offsets" is now type "string", no stored.

* Managment scripts finally offcialy added
* All scripts moved to bin/
* Auto remove newrelic_agent.log
* Adjuest rank.coffee and query.coffee for new schema
Found the proper solution for the "object" problem

Minor fixes in startup files (already fixed on the server).
Do not ignore ES errors

Today Spoant spend 5h just discarding crawled results after ES
went down

Fixed a typo too. I've got to admit trhrough "Cheerful" analyzis
is an intrestinc concept :p
Updated all the pacakges
Improved build script and more taks

You can now call 'gulp serverd' and 'gulp crawlerd' to start
server and crawler background processes with forever.

'gulp make' compiles files wihtout watching - really an alias
for 'gulp scripts web'.

'gulp prepdb' prepares and CLEARS ES for deployment (ahead of time
mapping settings)

* README.md was added to describe installing on Python 3 systems
* Jade removed from depenencies
Moved all the crawl-rank scripts to one folder
Fixed the redis problem (Hopefully)

The queueing mechanism is now full driven by Elasticsearch. Please
see database.coffee for details.

elasticsearch-setup.sh now can reseed and remap only ceartin part
of the database. Options include:

  crawler - Clear and remap crawler queue
  search - Clear and remap search index
  seed - Seed links with sites specfied in seeds.txt

* Other elasticsearch setup scripts are no bundled with spotant
* Nginex stuff separted from root folder
* Much more versbose crawler debugging mode
* Turn off info logging for elasticsearch
* Implement proper 'offset' setting and tracking
Updated changelog on the website
Crap! Quickfix for Express

I removed 'jade' from package.json. It was a mistake
Fixed production perl problem (by using more perl)
Added more elasticsearch config

Getting it to run on a Digital Ocean micro instance is very tricky
Added a TODO list
Added Terms & Conditions

* Removed SO and HN from seed list (too spammy)
* Show number of results during a search
Experimental redesign

* "Why spotant" is curretnly duplicated in both "/" and "/why"
