Renaming the special methods of the formatters....

Renaming the special methods of the formatters. The IPython formatters use special methods to compute the format of objects. These special methods have names like "__html__", but with this commit these have been changed to "_repr_html_". I have also added a Javascript formatter and fixed a bug in pylab tools in getfigs.
