As a Wikisource user, I want the Wikimedia OCR gadget to be moved to the All-and-every-Wikisource extension, so that all Wikisource users can be able to view, access, and use the Wikimedia OCR tool with no special installation process required.
Resources:
- OCR Improvements Project page -- note that the tool is called Google OCR on the page
- Notes on Google/Wikimedia OCR
- Documentation on Wikisource extension
Acceptance Criteria:
- Move Wikimedia OCR gadget to the Wikisource extension
- The API endpoint for the tool should be configurable (e.g. $wgWikisourceOcrEndpoint) and default to https://ws-google-ocr.toolforge.org/api.php (the current value), so that it can be customized for Beta Wikisource and for the new tool's URL (when that is available).
