GitHub Release

In #167, @lddubeau made many improvements to edge cases that have plagued users:

• Overhauls rejectedWith to behave more like Chai's throws asserter.
• Updates .fulfilled, .rejected, and .rejectedWith to change the asserter target to the fulfillment value or rejection reason, so that further assertions with .and act on them.
• Updates .fulfilled, when successful, to return a promise that fulfills with the fulfillment value
• Updates .rejected and .rejectedWith, when successful, to return a promise that fulfills with the rejection reason

Also, Chai as Promised now only supplies a CommonJS-style module. To get AMD or <script>-compatibility, use a bundler tool like browserify.
