[JsonPatch]: PathHelpers.NormalizePath should allow spaces and \\ characters

[pranavkm]

Consider

public class Person
{
    [JsonProperty("Person Name")]
    public string Name { get; set; }
}

A patch can be sucessfully applied to this property as

var doc = new JsonPatchDocument
{
    Operations = 
    {
        new Operation("add", "/Person Name", null, "New Name"),
    },
};

doc.ApplyTo(person); // This works correctly.
doc.Add("Person Name", "New Name") fails

Same deal with back slashes. The invalid char check in that method is kinda unncecessary.

@ajaybhargavb, can you please look into this? Thanks!

[ajaybhargavb]

Yup. The spec https://tools.ietf.org/html/rfc6901 does not disallow whitespace or backslashes. I'll send a PR.
