Support setting routes for serving static files

[yanecc]

This is a work in progress, aiming to address #60
There is still much work to do ...

It can work as expected now but with unhandled errors.

Closed stream (IO::Error)

Can you investigate why does this happen?

Relevant issue: crystal-lang/crystal#14566

Should be fixed by #66

[yanecc]

The code works well now and is reviewable.

@yanecc Can you provide an example?

I am going to modify this code a little bit to be a bit more Grip-esque, I will update the documentation with the news.

@yanecc Can you provide an example?

Sure, here is a simple illustration.

class Application < Grip::Application
  def initialize()
    super(environment: "development", serve_static: true)
  end

  getter host : String = "127.0.0.1"
  # getter pubilc_dir : String = "./public"
  getter static_routes : Hash(String, String) = {
    # "/"        => "./public",
    "/foo/bar" => "./dir1",
    "/baz"     => "./path/to/dir2",
  }
end

# By default, when serve_static is set to true, public_dir will be set to "./public".
# You could use pubilc_dir to set the static directory.

# If static_routes is set, pubilc_dir will be overwritten.
# GET http://127.0.0.1          #=> 404 Not Found
# GET http://127.0.0.1/foo/bar  #=> 200 OK -> ./dir1/index.html
# GET http://127.0.0.1/baz      #=> 200 OK -> ./path/to/dir2/index.html

I updated the version of Grip to 3.0.0 since I implemented breaking changes and will update the documentation to reflect your changes as well, added a new DSL macro.
