Ticket 1394 - Helper isolation
 r1319@iwill:  jeremy | 2005-06-15 01:10:00 -0700
 Formulate a test case for helper isolation.
 r1331@iwill:  jeremy | 2005-06-15 15:21:07 -0700
 Update changelog
 r1332@iwill:  jeremy | 2005-06-15 15:21:30 -0700
 Remove superfluous, broken layout_test
 r1333@iwill:  jeremy | 2005-06-15 15:24:10 -0700
 Use an anonymous Module to store helpers per-class instead of tossing them all in template_class.  Create a new helper module for subclasses which includes its superclass' helper module.  Remove unnecessary ActionView::Base.controller_delegate.  Update helper tests.
