Issue: [4.1 Beta 1] Widgets: Help overlay edit/delete buttons for non-admin, contents overflows outside container

These issues all relate to the widget help area (linked from wiki code list [widget] section) on the vaultwiki.org xf demo .

1) edit and delete buttons are shown that link to admin.php, despite viewing with a non-admin account. E.g. : https://www.vaultwiki.org/xf-wiki/in...p&helpid=10003. In an overlay, these buttons appear above the content next to the title.

2) widget help overlay contents is not scrollable and can overflow beyond the bottom boundary of the overlay box. Compared to XenForo 2's contact form overlay, body is missing the class "is-modalOpen is-modalOverlayOpen" (toggled when overlay is open). I think this should be fixable by changing the click handler to data-xf-click="overlay" (unless there are other reasons for using data-vw-trigger="help"). With this change and the the inline-style height property for .vw-overlay-scrollable removed, the widget help overlay is properly scrollable.

3) Navigating directly to the URL index.php?wiki-tools/&do=help results in an undefined index: helptype error. I haven't come across any actual links to this exact URL, but then there are people like myself who manually remove the helpid from the url to see what happens
