Title: Change behavior of ipython notebook --port=...

Previously ipython notebook took the port parameter as a suggested place to
start looking for open ports. With this commit:
* `ipython notebook` : start at port 8888 and try random ports until success
* `ipython notebook --port=1234` : use port 1234, failing if it is not available

Closes gh-1750.
