[with patch; positive review] notebook -- help(foo) in the notebook should not word wrap

[was]

This is *very* easy to implement:

1. Make it so help is a wrapper around internal help. (Already true?)

1. If in notebook then display the result using html and pre. Done.

The attached patch does this:

  1. Wrote new version of help command for the notebook.
  2. Slightly modified how truncation is done to account for 1.	 While I was at	it, I fixed another
     but where reloading a page would put multiple "output truncated" messages at the top of the page.

This is ugly -- scroll down:

help(interact)

I don't know if this is worth a fully negative review, but I think this looks like crap. Perhaps a pre tag would make it all better?

I completely rewrote help(...) to address the referee remark and to make help(...) vastly more robust when the output is MASSIVE (which it often is). Try, e.g.,

import numpy
help(numpy)

with the new version, and your browser will *not* get killed. I had my browser crash in class when teaching with the old version.

Of course the issues with help(interact) are also fixed.

Apply both patches, in order.

Failed to apply :(

Works for me.

Merged both patches in in Sage 3.0.2.alpha1. The dependecy tree is borked since part 2 depends on #3024 being merged. D'oh
