Proposal to rename the mockdata files with a reference to the block

[pigeonfresh]

data/c01-hero-default.yaml
data/c01-hero-*.yaml

A naming convention like this would make it easier to open data files for a specific component in editors.

Works for me :)

For legibility I would suggest snake-case, especially since most editors have a smart enough search system to deal with different casings.

@pigeonfresh I think you meant kebab-case. PR looks good, but I don't agree with *-data.yaml. All yamls are data, and we're not doing *-template.hbs or *-styles.scss.

Can we remove that?
