Inject requirejs in notebook and start using it.

Mainly because the behavior of Marked change when require is injected.
So only apply the modification needed for marked to behave.
start using bootstrap
bootstrap base, auth
overriding baseLineHeight is not a good idea
jquery-ui.custom has been renamed
bootstrap menubar
bootstrap toolbar
shrink login button
bootstrap tree
remove unused jquery-ui checkpoint
don't use $(document).append (it's wrong and broken)
use components jquery-ui
bootstrap dialogs
tree style tweaks
bootstrap button output area
ipython-main-app should be a bootstrap container
