Changes all the YouTube links on a page to YTPak links
As YouTube is blocked in Pakistan, so instead of using the proxy sites we can use the so-called "Pakistani versions" of YouTube like YTPak and Playit.pk
This script converts all the YouTube links on the page with YTPak links. So now you don't have to search that specific video on YTPak. All you need is to click on the same old YouTube link and this will take you to the Video on YTPak. However as YTPak currently doesn't support the embed feature, so embedded videos will be redirected to Playit.pk links
Instructions: This script will automatically change the links, but for some reason if links are not changed, press (alt+z) to run the script again without any page refresh.
