URL backslash fix + Prettifying JSON + Exclude paths

Fixing url backslashes

• path.join in windows seems to convert all fordslashes into backslashes, regulating to the system path structure.

Prettifying JSON

• Tests were prettified but stopped working, simple patch.

Added exclude : [path/, ...]

• Grunt-tree doesn't support "Building the files object dynamically". So in return, excluding files was not available.

//To exclude any directory or path, simply add an array of URIs:
options : {
    exclude : [
        'css/style.css',
        'img/',
        'js/bootstrap/secret.js' ]
}

Note: All paths are relative to the "current directory" / "cwd"

1. Fixing url backslashes:

Why use fordslashes (slashes) in all system? I thought it depend on system.

2. Prettifying JSON

This is ok, and different people have different indent. So, we can add it to config?

3. Added exclude : [path/, ...]

Pretty good.

UNC Paths

• You are correct, it varies on each system (UNC paths). I have made it optional and off by default.
  Return files in UNC paths via: uncpath : true
• This does not interfere with format/ext options now :)

Prettifying JSON

• Made optional like requested. To turn on use: prettify : true

Sorry for reply later.

Can you improve the document and tests? And I can publish to new version
