Fixes for incomplete ECMAScript 5 implementations

Fix issues in early ECMAScript 5 implementations.

Usage

Fixed function can be implemented to override native one, for that use implement module, e.g.:

require('es5-fix/date/parse/implement');

Or you can use fixed version independently e.g.:

var parse = require('es5-fix/date/parse');

Implemented fixes:

Date.parse (es5-fix/date/parse)

There's probably no single implementation that provides perfectly compliant version of Date.parse, this version fixes that. Implementation is based on es5-shim version.

Object.defineProperty (es5-fix/object/define-property)

Addresses the issue where re-definition of non writable properly has no effect. Old versions of Webkit are vulnerable to that. See:

• http://code.google.com/p/chromium/issues/detail?id=72736
• https://bugs.webkit.org/show_bug.cgi?id=54289

Additionally it fallbacks to direct assign if defineProperty crashes with defineProperty is not supported on DOM objects (happens in Safari 5.0)

Object.defineProperties (es5-fix/object/define-properties)

Makes sure that fix for defineProperty also applies to defineProperties
