Add `stack hoogle --server` command

[chrisdone]

Which would run stack hoogle -- --server --local. --local is needed to be able to click links to local files.

I wonder if Hoogle should launch a web browser on --server, and then when the web browser disappears it could close the server. Maybe as a stack hoogle --launch? I'm quite happy to adjust the semantics/API of Hoogle to make this better for stack users.

[chrisdone]

It could be a handy shortcut. The only reason you start the server is to see the web page after all.

Ticket raised at ndmitchell/hoogle#175.

Small correction, I think it should actually be stack hoogle -- server --local.

[fosskers]

Can this be closed?

[ndmitchell]

stack hoogle -- server --local works today so I think everything is good.
