Some readme updates
Failover for galaxy URL methods implemented

See docstring for more information
Merge branch 'failover'
Automatically trust the notebook we write out
add additional button to the IPython Notebook to save the document to galaxy
add new JS files to save the NB to Galaxy
Untested code to whitelist only the connecting IP

This has not yet been tested but should work...except for the API call from docker to galaxy. Not
sure how that's going to work :/
Merge branch 'iptables' of github.com:bgruening/docker-ipython-notebook into iptables
