* Fix typo in task description
Before it cleared out user records only (e-mail, password) without
freeing up the associated username (account record). Furthermore, since
these records have no dependent records (due to no user activity)
they can be deleted quickly with delete_all instead of destroy
* 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

Fix#441, fix#596, prerequisite for #1064
* Fix JS test
* Add rake task to generate static avatars/headers from GIF ones, add test

is to be treated like images in terms of behaviour, but are videos by file
type.
