Bug 17469: Add missing sample notices to fr-CA web installer

Adds missing notices to the fr-CA web installer:
- MEMBERSHIP_EXPIRY
- PASSWORD_RESET
Renames RESERVESLIP to HOLD_SLIP

TEST PLAN
---------
1) Apply the first patch
2) prove xt/sample_notices.t
   -- it should fail for fr-CA.
3) Apply the second patch
4) prove xt/sample_notices.t
   -- it should pass.
5) run all tests (prove t; prove xt)
   -- they should generally pass
6) run koha qa test tools

NOTE: Split test patch from fix patch, so could prove problem
      exists easily.
