Project cleanup

Removed unused temp, test, and unrelated files
Updated service apis (elasticsearch, redis, couch) to use values from config rather than hardcoded values
Updated code to use tasks as defined in config rather than hardcoded function references
Added new index configuration and updated field mappings to better suit search requirements
Removed use of bloom filter on whitelist and blacklist in favor of an in-memory set for equally fast lookups without false positives
Updated and renamed scripts for starting celery workers and harvesting request
Updated Readme to reflect new configuration format and include instructions on what the scripts do and how they can be used
Updated requirements.txt with package versions to take advantage of newer functionality
Added development scripts and configs for mac/homebrew users (like myself) to easily start up an elasticsearch and redis instance for testing purposes
