Late 0.3 Release

I add a popup feature for popcorn in my 0.3
This popup allow user to watch the video in a new popup window, and the original window's player will be paused and hiden while the popup window is existing.
If the user close the popup window, he/she can restore the original one by click the restore button. (In my origin plan, This should be done automatically, but the onunload method cannot be called correctly)
For now, this feature cannot store user's watching time point, so user has to start from begining, I'm looking for a way to achive that.
