Remove script templates for Javascript

[agarcialeon]

Javascript support has been deprecated in Unity3D as a programming language (note that I'm not pointing to Javascript plugins when you export for WebGL platform). So script templates should be removed from the library or move them to a legacy folder.

yes, i'd say just remove - no need to keep (since they are totally useless)
