-iplib.py: added InteractiveShell.getapi(). New magics should be

written doing self.getapi() instead of using the shell directly.
-Magic.py: %store now allows doing %store foo > ~/myfoo.txt and
%store foo >> ~/myfoo.txt to store variables to files (in clean 
textual form, not a restorable pickle).
