Fix for #3719

%-d is not a valid strftime format on windows.
Add link_or_copy to IPython.utils.path
Use link(2) when possible in nbconvert
Fix a couple typos
Add cwd to sys.path
This makes transformers and filters in the cwd load
from dotted object names.
Better name `init_syspath`
py3 doesn't have nested, py2.6 doesn't have multiple context managers
cleanup terminal console iopub handling

ensures IOPub for a given cell is handled before drawing the next prompt.

Follows logic elsewhere using `status=idle` to signal end of output for a given cell.
Prior to this, early execute reply could result in some output being printed after the prompt for the next input.
remove unused current_msg_id
relax wait_for_kernel timeout

wait_for_kernel should be done very differently,
but I'm not certain exactly how.
Organized reveal's templates.
Add reveal/*.tpl path to setupbase.
Fixed typo in reveal/*.tpl path in setupbase.
Fixed path in setupbase, again...
Insert cwd to top of list
add Importing Notebooks example
Add ENOLINK constant
re-raise KeyboardInterrupt in raw_input

shortens traceback when KeyboardInterrupt is caught deep within zmq.

closes #3786
catch KeyboardInterrupt in debug

avoids traceback for ^C in ipdb.

also prevents KeyboardInterrupt from exiting debugger.
Is this actually desirable?
skip tests that require pandoc
