From 269b942a2bf7b022795e591d9b0ad04526ee7e09 Mon Sep 17 00:00:00 2001
From: Derek Jones <derek.jones@ellislab.com>

Subject: added ability to "extend" helpers * modified Loader to check for
 prefixed helpers in application/helpers folder * surrounded provided helper
 functions with if (! function_exists('foo')) conditionals so the user's
 helper functions take precedent.
