Andrew Nicols 16a34ae189 MDL-46375 core_files: Split parts of file_storage into new file system
This change moves all operations which deal with the fetching/updating, or
setting of files from the file_storage class into a new file_system class.

A new file_system can be specified in the config.php and used to replace
all relevant methods in order to move the file system component to an
alternative solution.

Question import/export formats
==============================

This directory contains plug-ins to supprt importing and exporting questions in
a variety of formats.

Each sub-module must contain at least a format.php file containing a class that
contains functions for reading, writing, importing and exporting questions.

For correct operation the class name must be based on the name of the plugin.
For example:

plugin: webct
class:  class qformat_webct extends qformat_default {

Most of them are based on the class found in question/format.php.
See the comments therein for more information.
