Uploading animated GIF outputs only first frame
Your ImageMagick library version is 3.5 years old.  I'd start by updating that to something newer. 

You didn't list the PHP Imagick extension version, but I'd bet it's out of date as well.  3.1.2 is the latest stable release.

Also, Craft will automatically try and detect if Imagick is installed and available via PHP, but it won't hurt to explicitly set the imageDriver config setting to imagick to be sure.


  Is there a way to disable image transforms for animated GIFs or GIFs in general?


Not currently, sorry.
