van der Grinten fix

add van der Grinten ('vandg')

[ 2138392 ] API doc for add_subplot()
Also fixing numerous problems with the documentation build. It seems that the change in plot_directive.py to use the "code" module to run scripts interferes with i18n in Sphinx (due to the overloading of '_' as a symbol). Changed to use the fewer-moving-parts imp.load_module() instead.

added two new projections ('mbtfpq' and 'gall')

removed numerical_methods from imports

fix typo
