Bug 10420 - Standardize spelling of "authorized"

Bug 10420 - Standardize spelling of "authorized"

This patch corrects instances of the non-[American]-standard spelling
"authorised" when used in text.

The following instances are corrected:

- In Administration -> Funds, the error message displayed if you do not
  have permission to edit a fund.
- In Administration -> Authorized values, the instructions linked to the
  "Libraries limitation" field.
- In Administration -> MARC bibliographic framework test, instructions
  related to linking to authorized values.
- In the course reserves add form, error messages referring to missing
  authorized values.
- In guided reports, error messages shown when an authorized value
  chosen as a report parameter doesn't exit.
