Release 0.1.13

[ktoso]

I thought I could release, but I'm lacking sonatype permissions.
Could you please release @2m?

Seth made a checklist #140 but we actually have most things done already, I also prepared the tag as well.

• tag https://github.com/typesafehub/migration-manager/tree/0.1.13
• release https://github.com/typesafehub/migration-manager/releases/tag/0.1.13

Seth's TODO / sanity check list:

• create milestone
  • https://github.com/typesafehub/migration-manager/milestone/9
• fix/merge any sufficiently important issues/PRs
• run Travis against latest Scala versions (past example: be 2.12.0-RC2 compatible #131)
• associate closed issues & PRs to milestone
• make next milestone, move open issues & PRs to it
• tag it (using signed tagging)
  • https://github.com/typesafehub/migration-manager/releases/tag/0.1.13
• sbt publishSigned

I'll post the 0.1.13 release announcement to scala-announce. (By the next time we release, scala-announce may be replaced by Discourse.)
