## Idle Session Logout: Client Browser based js Event Listener. 
/*
Notes: Logs Users out whether they are inactive|idle, have navigated to another Browser tab window or closed their Browser.
milliseconds: 60000 = 1 minute | 3600000 = 60 minutes
Applies to WordPress Post, Page & Comment page TinyMCE editors: 
Adding an Event Listener for the WordPress Post and Page Visual editing window or other instances of TinyMCE is not possible to do with TinyMCE outside of TinyMCE due to conflicting Event Listeners. If someone does NOT choose to disable ISL for TinyMCE instances, the native WP Confirm alert popup prevents the ISL redirect from occurring on WordPress Post and Page editors as long as some content has been entered into the TinyMCE visual editor in the Post and Page Editing windows. User is prompted to either allow the ISL redirect or cancel the ISL redirect if the most current Post or Page content has not been saved. If the most current content has been saved then the user is redirected by ISL and logged out of the site. The Event Listeners for the TinyMCE text textarea editor works normally.
Special Note for the WP Dashboard page:  An instance of TinyMCE loads in Dashboard > Activity > Comments section. ISL loads the standard js and not the disable ISL TinyMCE js.
Applies to all other instances of TinyMCE used by plugins and themes: 
wp_editor() instances Visual editor cannot have Event Listeners added outside of TinyMCE. If someone does NOT choose to disable ISL for TinyMCE instances, then if someone is idle for X minutes and focused in the TinyMCE Visual editor window and the ISL timeout fires then they will be logged out and all unsaved content in the TinyMCE Visual editing window will be lost.
TinyMCE Notes: 
Consistent element id to check for instances of TinyMCE: id='editor-buttons-css'
WordPress element id to check for Post, Page & Comment TinyMCE Editor: id="wp-content-editor-container"
.54.1: switched to Roles instead of using user_level
.54.1: Request URI Exclusion option|condition added
.54.2: Added Custom Roles
