Add a basic request function
If we add a basic
request :: Request *World -> *(MaybeErrorString Response, *World) which runs a query on cloogle.org, implementing a new frontend becomes trivial.
Another function could use a
String instead of a
Request to handle one-string queries like on cloogle.org.
(For this, we can use the doRequest function first created in https://github.com/camilstaps/clpm/blob/master/CLPM/Util.dcl#L15 and now used in multiple applications. It should be added to Internet.HTTP in Platform.)
