%autoreload magics is not escaped

[mwouts]

Some of my notebooks use

%load_ext autoreload
%autoreload 2

In the text representation of notebooks, the second line is not escaped, as autoreload is not a standard Jupyter magic.

List of magics to be escaped should be configurable, and include per default the most standard magics, so that I don't have to add #escape to the second line (current workaround).
