Extend Quote/Estimate custom name to other parts of the interface

I believe the custom label only applies to the actual document and any relevant fields within the document (e.g. quotation date, quotation total etc). It does not extend to the interface.

We could possibly consider embedding this label on the interface, but most likely only within the client area rather than the core interface. Right now we are very busy with a lot of house cleaning stuff, so it’s unlikely we can work on any new features in the next 4-6 weeks.
