Use hexadecimal values instead octal
Use hexadecimal values instead octal

Strict mode in ECMAScript 5 forbids octal syntax. This octal literals
are breaking the webpack compilation in upper packages like tangram-cartocss.

Mapbox have already [fixed this](https://github.com/mapbox/carto/blob/master/lib/carto/index.js#L104)

This PR changes the octal literals and uses hexadecimal ones.
