Compiler modification to have Apache v2 license in compressed class. Moved backupQueue function to core/queuer.php. Improved callback.php to always return JSON, even when dealing with error or success codes, cleaned up the fileAction in callback code. Core/io.php changes to check if a Node Preferential Location IS set AND is not null, as opposed to just checking if it is null. Changed all is_int checking to is_float as error codes are floats / doubles, not ints. New checking for if the file we are appending to exists, else it will act as if we are writing to a new file. Cleaned up fileActionHandler returning to always return JSON. Core/sys.php changes to ensure php-cli builds work with Metis, since some php-cli do not have DOCUMENT_ROOT set. Removed framework.php \o/.
