Added new functions to editor api - set/get_text so the
original form text can be determined from an editor.

When calling use_editor() you should first call set_text() with
the text that will be inserted in the form element.

There is also a new scheduled task for cleaning Atto autosave drafts.

The testsuite name is fed straight into a class_exists() in
PHPUnit_Framework_TestSuite. In some cases, e.g. cachestore_static, the
class does exist, it's then fed into a ReflectionClass, and the test fails.

The testsuite needs to not conflict with any classes which could be
autoloaded in Moodle core.

The logo for the clean and more themes will only be
displayed on the front page and login page as it was
replacing the header information on other pages within
Moodle, causing users to lose information on the page.
