Rename or somehow tag vimeo ss3 vids as being for SS3

[NightJar]

Although technically not directly related to this repository...
Currently there's a bit of confusion, particularly if someone new to the system googles and receives a link directly to vimeo. It's not clear that e.g. the _ss_enviornment.php file is not for the version they are probably trying to use (latest stable: ie. SS4).

If we could prefix the video names with e.g. ss3- or something similar (does vimeo support tags?) this could help relieve confusion.

Perhaps also adding a blurb at the top of the description for each video that links off to the latest stable release equivalent would also be more ideal.
