Inline dereferencing and fragments

json-schema-ref-parser appears to not support a portion of the JSON Schema spec regarding inline dereferencing (see http://json-schema.org/latest/json-schema-core.html#anchor31)

Reproducer: ` var test = { “id”: “http://some.site/schema#”, “not”: { “$ref”: “#inner” }, “definitions”: { “schema1”: { “id”: “#inner”, “type”: “boolean” } } };

deref.dereference(test, function(err, schema){ console.log(err, schema); }); `

Output:

"name": "SyntaxError", "message": "Invalid $ref pointer \"inner\". Pointers must begin with \"#/\"", "stack": "SyntaxError: Invalid $ref pointer \"inner\". Pointers must begin wit h \"#/\"

I understand that this is not a required part of the spec, however it is a SHOULD given that the implementation does support inline dereferencing in general.

I intend to support inline references in the next version of JSON Schema $Ref Parser, which I have already begun working on. 👍

Internal reference support is a should, however

All fragment identifiers that do not match the JSON Pointer syntax MUST be interpreted as plain name fragment identifiers.

The program crashes with an error on valid schemas because of lack of adherence to this clause. If it’s not going to support internal references, it should ignore them.
