Separate subprojects into individual repos

[joeha480]

Subprojects should be separated into individual repos in order to simplify the work process.

Projects to move (mark when moved):

• Dotify (dotify-cli)
• dotify.api
• dotify.common
• dotify.devtools
• dotify.devtools.gui
• dotify.formatter.impl
• dotify.hyphenator.impl
• dotify.task-api
• dotify.task-runner
• dotify.task.impl
• dotify.text.impl
• dotify.translator.impl

For each project, do the following:

• Create new repo and move code there, see http://stackoverflow.com/questions/359424/detach-subdirectory-into-separate-git-repository/17864475#17864475
• In the new repo
  • add a tag indicating that the project was previously a subproject (last_commit_as_subproject)
  • add a gitattributes file
  • fix gradle build (copy from the old gradle root-project as needed)
  • add gradle wrapper
  • update documentation
  • set up travis build
    • add travis config file
    • enable in travis
    • test service in github
    • add env variables to travis (SONATYPE_USER, SONATYPE_PASSWORD, REPO_REVISION)
• In this repo
  • remove reference in gradle root build
  • delete subfolder
  • review and update documentation

Everything is done, apart from some updates to documentation
