When avatar/header are GIF, generate static versions (#1428)
* When avatar/header are GIF, generate static versions. Account API returns "avatar"/"avatar_static", "header"/"header_static" Static version is the same as original for other cases Web UI de-animates avatars in toots, lists of users Fix #441, fix #596, prerequisite for #1064 * Fix JS test * Add rake task to generate static avatars/headers from GIF ones, add test
