Allow NBClassic to work with NB7 and ServerApp.base_url (#165)

* Allow NBClassic to work if ServerApp.base_url is set and Notebook 7 is installed
Also resolves an issue where New->New Notebook did not respect the "/nbclassic/" in the url if it was set
Personally not a fan of the var still being called base_url_prefix but wans't willing to make that big of a change
Closes #164

* Change name of url prefix to be more appropriate
Rename base_url_prefix to nbclassic_path
rename baseUrlPrefix to nbclassicPath
rename url_prefix_notebook() to nbclassic_path()
