Merge branch 'newkernel' into trunk with all new Qt console work....

Merge branch 'newkernel' into trunk with all new Qt console work. This provides a new main script, ipython-qtconsole, that offers a rich Qt widget capable of multiline editing, inline plots, html help and much more. This branch was developed over the last two months mostly by Evan Patterson, Brian Granger and Fernando Perez, thanks to the support of Enthought, Inc. The code is now in a good prototype stage, and it's being merged into trunk where further work, polishing and stabilization will take place.
