ALM-1187 Fix release build by manually editing external dependencies, bump to 0.1.3

The current build system cannot cope with sourceMappingURL directives included in the externally loaded `es5-shim.min.js` and `es5-sham.min.js`. As a temporary fix, golden-kestrel.js has been recompiled after those comments have been manually removed.

A note has been added to the README to document this unsatisfactory fix. If anybody has any better suggestions, please speak up! :smile:
