invalid function names in locallib.php

[Dan Marsden]

local functions should be prefixed with the frankenstyle name - eg:

convert_label_to_page should be:

format_tile_convert_label_to_page

please review all function names and ensure they are either namespaced or prefixed with the frankenstyle prefix
