 * ManagerQuickNav v:0.0.1j (BETA)
 * Last edited: 2014-04-09 14:26

 * AUTHOR: 
 * info@pepebe.de
 *
 * DESCRIPTION:
 * This plugin injects js to add new items to 'modx-action-buttons'
 * (the button group in the top right corner of the update resource window).
 * 
 *   ManagerQuickNav adds:
 *   - buttons with links to the previous or next resource in the current menuindex 
 *   - a combobox with links to the current parent resource and all siblings.
 * 
 * The plugin is especially useful with other plugins that hide child resources like:
 * - articles
 * - collections
 * - grid_class_key
 * 
 * USAGE:
 * 1. Create a new plugin and copy the content of this file into the plugin code textarea.
 * 2. Check the 'OnDocFormRender' system event and make sure the plugin is not disabled.
 * 3. Done.
 * 
 * OPTIONS:.
 * emptyText = (string) Placeholder text for combobox
 * width     = (int) width of comobox
 * newTitle  = (string) Tooltip text for the create new resource button
 * 
 * hide_close = (bolean) Hide obsolete buttons
 *
 * IMPORTANT:
 * This is just a proof of concept. 
 * 
 * 1. It assumes that the menuindex of a group of child resources looks like this: 0,1,2,3,...
 * Im sure this is not always the case. The final version will handle this problem in a better way.
 * If you have a good solution for this problem, send me a mail.
 * 
 * CHANGELOG:
 * v0.0.1a Initial Release
 * v0.0.1b Customizazion options for combobox settings
 * v0.0.1c Trigger MODx.releaseLock(MODx.request.id) before leaving current page.
 * v0.0.1d Added ManagerQuickNav to root Elements
 * v0.0.1e Added option to remove obolsolet buttons and and button to create a new resource with the same parent.
 * v0.0.1f Language settings for en and de
 * v0.0.1g New changelog
 * v0.0.1h Now also (somewhat) working with articles. @treigh: Thanks for your feedback.
 * v0.0.1i Now COMPLETELY working with articles!
 * v0.0.1j Link generations completly rewritten. Note2Self: Action ids are individual for EACH modx installation!
 *
