javascript - remove charset

[neoxx]

Some inline-javascripts come with a charset, e.g. in wp-admin/user-edit.php

<script type="text/javascript" charset="utf-8">

​http://validator.w3.org/ complains:

Element script must not have attribute charset unless attribute src is also specified.

In total I found three occurrences which are all fixed by the attached patch.
