The button is no longer in the file menu

- After reading and gathering input on the mailing list I decided to go
with Dennis's idea of making a button. Instead of it being greyed out it
is hidden until you've recorded a video.

-I thought it was better to make this as a suggestion of what I thought
could be possible instead of letting the pull request sit idle.

-If/when Travis fails I'll fix those up in the next commit.
