The default colored console output is unreadable

[jwarkentin]

When run in a console that supports colors (which is most these days), Jest will output the necessary escape sequences to color the output. That isn't getting stripped or interpreted in the HTML output at the moment which makes output like the following completely unreadable:

Error: [2mexpect([22m[31mreceived[39m[2m).[22mtoHaveLength[2m([22m[32mexpected[39m[2m)[22m

Expected length: [32m4[39m
Received length: [31m0[39m
Received array:  [31m[][39m

A simple way to solve this would be with a library that can convert the colors to HTML or strip them completely, such as this one which can do either. This could be a configurable option as well.
