Copy statik package into the generated artifacts

[rakyll]

So the user don't have to go get github.com/rakyll/statik in order to use the autogenerated artifacts.

Is this about generating some code that would trigger on go generate in the target package to rebuild the package from updated sources?

[dolmen]

Or is it about including the code of github.com/rakyll/statik/fs (instead of github.com/rakyll/statik mentionned in this issue) in the generated code to avoid the link dependency?

@dolmen, yes, it is about including the fs package in the generated package.
