Broken Semantic Release

[dlabrecq]

The semantic release appears to be broken. The version of semantic release was recently updated to ^15.0.0, but that change never successfully published a package. The latest release (19 days ago) had to be published manually.

Note that ^15.0.0 is currently installing 15.8.1, which requires Node 8. Travis is currently using Node 4.

In addition, package.json references commands that no longer exist. For example, pre and post should be --pre and --post:

"semantic-release": "semantic-release pre && npm publish && semantic-release post",
"semantic-release-post": "semantic-release post",
"semantic-release-pre": "semantic-release pre"
