// @description Replaces javascript links with normal links on ynet.co.il, and enables embedded video clips in articles (v2.7).

//
// This is a Greasemonkey (0.6+) user script.
//
// To install, you need Firefox http://www.getfirefox.com and
// the Firefox extension called Greasemonkey: http://greasemonkey.mozdev.org/
// Install the Greasemonkey extension then restart Firefox and revisit this script.
//
// To uninstall, go to Tools|GreaseMonkey|Manage User Scripts,
// select the script and click Uninstall.
//
// --------------------------------------------------------------------
// v2.7 - Major refactoring.
// - Instead of replacing the iframes with divs, the script replaces the iframes' content.
// - The script now waits for the image to partly load before it goes on checking its size.
// - All popups are made resizable.
// - When visisting ynet.co.il, a menu item is added to toggle direct video links,
// instead of embedding the player inside the page.
// If Ctrl is pressed the movie is always embedded.
// - bug fix: previously, some unusually named preview images were not shown.
// v2.6 - new! supports multiple videos in one page.
// - new! supports the Video section.
// - new! supports videos in mediazone.co.il windows.
// - new! spports embedded audio streams.
// v2.5 - updated to embed videos from Mediazone (Ynet's new streaming video provider).
// added NewsFlash links to the allowed popup list.
// v2.4 - fixed image size bug, and reworked JS links removal.
// v2.3 - remove JS links in talkbacks too.
// v2.2 - bug fix: preview images are also sometimes too big - now set to fixed size.
// v2.1 - bug fix: video clip size was sometimes too big.
// v2.0 - public release: rewrite of a previous script.
// Returns null if expr didn't match anything
