New feature: Movie to Gif

[davidgatti]

My Problem

There are many tools out there that can convert movies to GIF but they cost to much for what they do, have tragic UIs, or generate GIF with the wrong pallet color.

Solution

Use FFMPEG to convert images to GIF with the following features:

• Update the GIF pallet based on the color average of the movie, so the GIF actually looks nice
• Generate a GIF of the same resolution as the original movie
• Have the ability to set the scaling factor for the GIF resolution so if needed the output could be for example 2 x smaller, 3 x smaller etc.
• Make sure the output GIF is as small as possible.

And the Bash should not be interactive, it should accept parameters.
