LMS-2771 Extend Document Checks to cover footnotes

Feature Summary

Several requests have been made for Document Checks to pick-up various issues in Footnotes, that prevent SI’s from being successfully registered.

They are:

• Extend the leading/trailing space check to include figure spaces created by user entering a double space in a footnote - see LMS-2561 Resolved

• Ensure that SI and SSI citations are well-formed, e.g. not missing any full-stops - see lms-2629

• Check for incorrect spacing in chapter no - lms-1102
