/* ===========================================================
 * trumbowyg.allowTagsFromPaste.js v1.0.2
 * It cleans tags from pasted text, whilst allowing several specified tags

 * ===========================================================
 * Author: Fathi Anshory (0x00000F5C)
 * Twitter: @fscchannl
 * Notes:
 *  - removeformatPasted must be set to FALSE since it was applied prior to pasteHandlers, or else it will be useless
 *  - It is most advisable to use along with the cleanpaste plugin, or else you'd end up with dirty markup
