Item12359: Refactor the DESTROY routines

Timothelitt pointed out that open / close should not break encapsulation
by living in separate files.   Use a Local package definition to define
the DESTROY routine, so that lock/unlock and open/close live in the same
file.

Also add the qw(-nofoswiki) to any use Foswiki::Time statements, so that
eachEvent doesn't break when used from configure

Item12359: Wrong class name

Called File::EventIterator, should have been FileRolling::EventIterator

Also missed a field in Config.spec
