extra frames in gif

[DreadKnight]

I've started to make good use for this for my latest 3d deviations (more in the works), so big thanks again for making this ^^ http://dreadknight666.deviantart.com/gallery/697059/3D

It's very handy, though I found a small issue: if I render a sprite sheet, do some revisions and change the animation's length from 80 frames down to 60 or whatever, the extra frames will still remain in the tmp folder and they'll get used in the gif even if they're out of scope, creating unwanted results. So the create gif function should only use the frames needed, as currently defined in the blend file.

Also, in my tmp folder, the music player I was using was adding the album cover in there, which was included in the gif. Now I'm not using that default directory anymore, just as a note to others who bump into the same issue.
