/**
 * All connectors are defined here, instead of manifest.
 *
 * Matching connector is injected to the page after document_end event.
 *
 * Do not include jQuery - it is included by default.
 *
 *
 * Supported fields:
 *
 *    label
 *          - label to be shown in options to enable/disable the connector
 *          - be careful with renaming, as connector disable state depends on the label
 *
 *    matches
 *          - array of positive matches in format described in Chrome Ext. Dev. guide
 *          - connectors are processed in order and the first match is used; you can use
 *            this behaviour to emulate exclude matches
 *
 *    js
 *          - array of paths of files to be executed
 *          - all executions happen on or after 'document_end'
 *
 *    allFrames (optional)
 *          - boolean value representing InjectDetails.allFrames
 *          - FALSE by default
