Remove the "Stop" action menu, which provided the following two options: "Now" and "After Current Track".

Reasoning for removal:
* It added an extra sub-menu in the systray menu. When you pressed Stop, another menu cames up, which was a hassle.
* It added an extra arrow in the main toolbar, which looked quite ugly and confusing.
* Seems that the "Stop After Current Track" feature was not very popular.

If anyone is against the removal, please speak up now.
