Bug 14362: Regression tests

Bug 14362: Regression tests

This should trigger the error. Attempts to shift system time
zones did not make sense as to the number of failures.

Added Time::Fake dependency, if it isn't installed these extra
tests don't run. There is a nice skip message about it.

Added License text.

TEST PLAN
---------
 1) apply test patch
 2) sudo dpkg-reconfigure tzdata
    -- set your system time to GMT (Africa/Abidjan)
 3) prove t/Circulation/AgeRestrictionMarkers.t
    -- should not fail, even if you change system
       time to any time.
 4) sudo dpkg-reconfigure tzdata
    -- set your timezone to Eastern
 5) sudo date -s"2015-06-18 21:15:00"
 6) date
    -- should be past 9pm Eastern timezone
 7) prove t/Circulation/AgeRestrictionMarkers.t
    -- kaboom!
 8) sudo date -s"2015-06-18 12:00:00"
 9) date
    -- should be noon Eastern timezone
10) prove t/Circulation/AgeRestrictionMarkers.t
    -- success?! Time sensitive tests are bad tests.
11) sudo apt-get install libtime-fake-perl
12) prove t/Circulation/AgeRestrictionMarkers.t
    -- kaboom!
    -- changing timezone to anything other than GMT
       should trigger a kaboom.
13) apply fix patch
14) prove t/Circulation/AgeRestrictionMarkers.t
    -- should work all the time.
15) less t/Circulation/AgeRestrictionMarkers.t
    -- the license text should be similar to
       http://wiki.koha-community.org/wiki/Coding_Guidelines#Licence
16) koha qa test tools.
