/**
 * Name: Quick Comment
 * Description: Two click comments
 * Version: 1.0
 * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
 *
 * Provides a set of text "snippets" which can be inserted into a comment window by clicking on them.
 * First enable the addon in the system admin panel.
 * Then each person can tailor their choice of words in Settings->Addon Settings in the Qcomment
 * pane. Initially no qcomments are provided, but on viewing the settings page, a default set of
 * of words is suggested. These can be accepted (click Submit) or edited first. Each text line represents
 * a different qcomment.
 * Many themes will hide the qcomments above or immediately adjacent to the comment input box until
 * you wish to use them. On some themes they may be visible.
 * Wave the mouse around near the comment input box and the qcomments will show up. Click on any of
 * them to open the comment window fully and insert the qcomment. Then "Submit" will submit it.
