Hardbound thesis submission formatting requirements from Cambridge University Board of Graduate Studies have changed since this template was last updated in 2018. Some of the changes could not be satisfied without modifying the class file, so this patch tweaked some details to provide functionality to comply with the latest Cambridge regulations.

Changes include:
- `abstract' option (abstract-only mode) now hides title page, nomenclature, and references as well (class file and thesis.tex)
- New class option `ntabstract' to print name and title onto abstract even when bound into the whole thesis (class file)
- Abstract now comes before Acknowledgements (thesis.tex)
- Default horizontal margins now defined using `width' rather than `ratio', so that bindingoffset no longer causes print and web editions to have different pagination. (class file)
