Bug 33076: Add context to "Quotes"

A quote as a part of quoted text and a quote as
part of the acquisition process need to be
translated differently at least in German.
This patch adds context to the terms, so we can
do that.

To test:
* Go to Tools > Quote editor
* Verify the heading of the page reads "Quotes"
* Enable EDIFACT system preference
* Go to Administration > EDI accounts
* Add a new account save
* Verify the table heading reads "Quotes"
* Apply patch - nothing should change

Verify the translation process:
* Run: gulp po:update --lang de-DE
* Verify the "Quotes" appear now separated by
  different context in
  misc/translator/po/de-DE-messages.po
