Stop using CMD with Windows

The current Windows incarnation is brittle:

it survives ampersands, but not other characters:

package main
import "github.com/pkg/browser"
func main() {
   browser.OpenURL("http://example.com?aa bb&cc")
}

better would be to call RunDLL32, no replacer needed. Examples:

rundll32 url,OpenURL "http://example.com?aa bb&cc"
rundll32 url,FileProtocolHandler "http://example.com?aa bb&cc"

Or call browser directly via the BROWSER environment variable. This is what Python does:

import webbrowser
webbrowser.open('http://example.com?aa bb&cc')

Or better still would be to call ShellExecuteW on Windows:

This is what D does:

import std.process;
void main() {
   browse("http://example.com?aa bb&cc");
}

and Nim:

import browsers
openDefaultBrowser("http://example.com?aa bb&cc")

pkg / browser
