Update dependencies

Trying to track down a "Error: WebGL: getExtension('MOZ_WEBGL_lose_context'): MOZ_ prefixed WebGL extension strings are deprecated. Support for them will be removed in the future. Use unprefixed extension strings. To get draft extensions, set the webgl.enable-draft-extensions preference." warning on Firefox 29.0, noticed gl-tile-map was still on webglew ~0.0.0, updated it to ^1.0.2 + the other deps.
