python 2 and 3 compatibility without 2to3
apply some fixes :
- apply (deactivated in setup.py now)
- repr (deactivated in setup.py now)
- print (only in modules with print >>)
- raise (partially)
don't touch deathrow and quarantine.
There's nothing there we should be running python tests on, and
occasionally python files may appear there that cause problems to nose
(e.g. mathjax ships a non-py3 valid conf.py that breaks py3 testing).
brutally replace all `exeption <type>, <name>:` by
`exception <type> as <name> :`
`exception <type>, <type> :` should not be present anywhere in the code
anymore, or should be present with explicit tuple as
`exception (<type>, <type>)`
this improve the current css of the print page and add css to the
classical notebook with print as target to get a better print view ant
the ability to directly print a notebook without going through the print
view
Fix spurious appearance of the #fontarea when fonts don't have any problem; also remove loud dialog when problematic font is detected and simply adjust baseline. Users will have a slightly offset baseline for bold/italic highlights, but without any functional problems.
Fixes#2005.
Clean BG processes created by %%script on kernel exit
* uses less forceful shutdown of kernels in the notebook, allowing atexit machinery to fire
* enables daemon BackgroundJobs
* cleanup %%script --bg subprocesses at shutdown
minor notebook startup/notebook-dir adjustments
* change inaccurate / distressing "Overwriting profile..." log message
* `ipython notebook path` results in setting notebook-dir if it's a dir,
rather than unconditionally setting file-to-run
* file-to-run overrides no-browser
* kernels start in the notebook dir, rather than the Server's cwd
* notebook dir is validated, and created if it doesn't exist (only if parent exists, like ~all other such things)

second attempt at scrolled long output
Some amount of CSS tweaking will probably want to be done before 0.13 final,
but this is good enough for beta.
closes#1553
Cell/Worksheet metadata
* metadata dicts are attached to cells and worksheets
* restores collapsed flag to the nbformat - this change happened in the refactor, and was undocumented, and possibly accidental. But we should either document it or fix it, and this includes a fix.
* adds a new field, `nbformat_minor`, used to denote minor bumps of the notebook format that expose new capabilities but don't prevent loading by older clients.
* Add a warning in Javascript if loading a multiworksheet notebook (which will exist in the future) as current JS code will only save the first.
