functions not following naming conventions

[danmarsden]

When a plugin implements it's own functions these need to be prefixed with the plugin frankenstlye name..

for example if you have a function called "update_course_module_preferences" the correct name to use would be "block_enhance_update_course_module_preferences" (with the block_enhance used as the prefix)
