-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).

a = !ls, a = %alias now work (captures output or gets ret val for aliases) IPApi.meta() provides session data storage for extensions. %alias without args returns a list of tuples instead of printing a list. __IP.meta is now Struct instead of dummy class "Bunch"

whoops, lasth commit was an accident - but it works. It made input prefilter configurable. This checkin fixed argv saving properly

mods

Provide "realistic" sys.argv for scripts run via ipython command line invocation

- Small fix to demos to flush stdout on each printed block.

ipapi rehaul, moved api methods to class IPApi. Usage didn't change much. Launcher methods now allow specifying initial user namespace (in order to be useful for users who embed ipython).

Merged 1071-1076 from banches/0.7.1

result_display can return value. ipapi.is_ipython_session(). %paste -> %cpaste.

Made %paste sentinel configurable
