	=item * &excess_filesize_warning()

	Returns warning message if upload of file to authoring space, or copying
	of existing file within authoring space will cause quota for the authoring
	space to be exceeded,

	Same, if upload of a file directly to a course/community via Course Editor
	will cause quota for uploaded content for the course to be exceeded.

	Inputs: 6
	1. username or coursenum
	2. domain
	3. context ('author' or 'course')
	4. filename of file for which action is being requested
	5. filesize (kB) of file
	6. action being taken: copy or upload.

	Returns: 1 scalar: HTML to display containing warning if quota would be exceeded,
