Updated plugin documentation * Added unit test for the bangs plugin * Fixed a unit test and added 2 more for bangs plugin * Changed back to default settings.yml * Added myself to AUTHORS.rst * Refacored working of custom plugin. * Refactored _get_bangs_data from list to dict to improve search speed. * Decoupled bangs plugin from webserver with redirect_url * Refactored bangs unit tests * Fixed unit test bangs. Removed dubbel parsing in bangs.py * Removed a dumb print statement * Refactored bangs plugin to core engine. * Removed bangs plugin. * Refactored external bangs unit tests from plugin to core. * Removed custom_results/bangs documentation from plugins.rst * Added newline in settings.yml so the PR stays clean. * Changed searx/plugins/__init__.py back to the old file * Removed newline search.py * Refactored get_external_bang_operator from utils to external_bang.py * Removed unnecessary import form test_plugins.py * Removed _parseExternalBang and _isExternalBang from query.py * Removed get_external_bang_operator since it was not necessary * Simplified external_bang.py * Simplified external_bang.py * Moved external_bangs unit tests to test_webapp.py. Fixed return in search with external_bang * Refactored query parsing to unicode to support python2 * Refactored query parsing to unicode to support python2 * Refactored bangs plugin to core engine. * Refactored search parameter to search_query in external_bang.py
