Redirect back to the accreditation wrapper after each change to keep user focused on the accreditations

[Richard Lyders]

This is a small tweak to keep the user's focus on the accreditation area of the ticket form and avoid the need for the user to keep scrolling down when several changes are being made to the accreditations. Since this now displays the HTML ID of the accreditation wrapper, I thought it helpful to make the HTML ID of the main container a configurable item so as to be able to align this reference with whatever might make most sense to the user.

Specific changes:

1. webui_wrapper: new config entry for the ID of the HTML container for accreditations
2. appended all redirects with reference to the accreditations HTML wrapper so the user doesn't have to keep scrolling down to get back to what they just edited in the accreditations area

This enhancement can be closed as a duplicate of enhancement #13289 considering I've attached a complete unified patch to #13289 with this and all other changes I've implemented.

Complete patch attached with all changes to date ... (the attachment description erroneously calls it a "complete path".

Thanks again for this plugin. We are getting some good use out of it.
