	Video Player for Blink videos. Meant to play tutorials.
	I doubt I'll be able to add any type of seeking.

	I'll probably make a program in C# to easily get at
	Youtube versions of the	tutorial videos.

	This is Spagetti code :( - hekar

	Should be called tutorialplayer :/ - Me (Hekar)
	
	talking to myself...
