orphus target for corrections bug

[funderburkjim]

There is a method for submitting corrections available in simple-search.

For description, see sanskrit-lexicon/csl-corrections#26 (comment)

This involves:

• listview.php which loads
• orphus.customized.js

The orphus Javascript is initialized in listview, and sets 'correctionsUrl' parameter with value
https://www.sanskrit-lexicon.uni-koeln.de/php/correction_form_response.php

This value is changed to
'https://www.sanskrit-lexicon.uni-koeln.de/scans/csl-corrections/app/correction_form_response.php

Now submissions via orphus system go to the correct place (csl-corrections/app/correction_response/ directory
on Cologne server.
