Add support for unescaping URL encoded VirtualMachine names

[atc0005]

For example, a VM named server1.example.com - Q/A Web in the vSphere inventory is listed as server1.example.com - Q%2fA Web when printing the Name field.

This isn't necessarily a problem, but it would be useful to list VMs in the same format as they're shown within the web UI.

This would necessitate wrapping all access to the Name field with a helper function of some kind. It is likely that other fields would be similarly affected (e.g., Folder names).

Mockup:

package main

import (
	"fmt"
	"log"
	"net/url"
)

func main() {
	sampleText := "Q%2fA Web"
	expectedText := "Q/A Web"

	resultText, err := url.QueryUnescape(sampleText)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(resultText)
	if resultText == expectedText {
		fmt.Println("Successful unescape")
	}
}

Output:

Q/A Web
Successful unescape
