Make mojo and sky dart packages deployable

Make mojo and sky dart packages deployable

The packages produced from this CL were deployed
as v0.0.1:
https://pub.dartlang.org/packages/sky
https://pub.dartlang.org/packages/mojo

There is still no tool included with the sky
package due to pub's inability to run anything
other than Dart:
https://code.google.com/p/dart/issues/detail?id=22877

I'm likely just going to write a dart version
of my "sky" script. :(

dart_sky is just a list of parts.  We'll need to cat them all together somehow.
