Set default figure size in inline mode to (6,4)....

Set default figure size in inline mode to (6,4). Otherwise, unless users have configured it manually, the default of (8, 6) that mpl uses produces giant figures on the canvas that aren't particularly useful. Since controlling the figure size in inline mode may be a more frequent need, added a top-level helper (most people won't know what the right call is to make otherwise).
