get rid of most slowdown at notebook loading. 1) Do not setOption('mode',new_mode) on CM if new and old mode are the same. It triggert **a lot** of calculation of bounding box in the end. 2) Do **not** select cell when loading the notebook it triggers **a lot** of CM even that check visible things and so on and so forth. So add a option to add_cell_at_index not to select it 3) jQuery $.attr has some magics, but has a slight overhead on real native ELEM.setAttribute DOM method. Seem slight improvement when loads of PNGs on one page

Documenting What's New

When making a new pull request that either adds a new feature, or makes a
backwards-incompatible change to IPython, please add a new .rst file in this
directory documenting this change as a part of your Pull Request.

This will allow multiple Pull Requests to do the same without conflicting with
one another. Periodically, IPython developers with commit rights will run a
script and populate development.rst
with the contents of this directory, and clean it up.

Files which describe new features can have any name, such as
antigravity-feature.rst, whereas backwards incompatible changes must have
have a filename starting with incompat-, such as
incompat-switching-to-perl.rst. Our "What's new" files always have two
sections, and this prefix scheme will make sure that the backwards incompatible
changes get routed to their proper section.
