Subject: [PATCH] Bug 26515: Add Koha::Acquisition::Order->cancel

This patch introduces an OO replacement for DelOrder. It does the same
thing, but raises exceptions instead of returning error values. It is
designed so the caller catches the exceptions and (1) presents the
situation to the end user or (2) does the right thing depending on the
exception.

To test:
1. Apply this patches
2. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/Acquisition/Order.t
=> SUCCESS: Tests pass!
3. Read the tests carefully to understand how they cover all use cases.
4- Sign off :-D
