Remove superstatic package

Install and uninstalling superstatic doesn't work on Node 8 at the time of
writing:

    $ npm install -D superstatic@6
    npm ERR! code ENOTSUP
    npm ERR! notsup Unsupported engine for got@5.7.1: wanted: {"node":">=0.10.0 <7"} (current: {"node":"8.11.3","npm":"6.3.0"})
    npm ERR! notsup Not compatible with your version of node/npm: got@5.7.1
    npm ERR! notsup Not compatible with your version of node/npm: got@5.7.1
    npm ERR! notsup Required: {"node":">=0.10.0 <7"}
    npm ERR! notsup Actual:   {"npm":"6.3.0","node":"8.11.3"}

This commit removes the package (using Node 6!) and it will have to be replaced.
