Hamish Friedlander 65030906ad BUGFIX: Add validation to fix open.silverstripe.org ticket #7494
When adding media via the HtmlEditorField dialog, the value of the URL field wasnt being validated. Youd get different errors depending on if the field was empty
or if it had text, but it didnt look like an absolute URL to HtmlEditorField#viewfile.

This adds some javascript validation to make the text field look like a URL field
