BREAKING: Support only node 6 and 7. Updated CI config

The introduction of source-locators breaks compatibility with
node-versions below 6, because the package 'handlebars-source-locators'
uses language features that are only available in node 6.

In addition, this commit introduces minor changes in the Travis-
configuration:

- "standard" is now a dev-dependency to enable controlled updates
  through Greenkeeper
- "thougth -d up-to-date" is run in Travis-CI to make sure the
  documentation is up-to-date
- Examples are not executed with a custom `console.log`-function
  that uses "json-stable-stringify" to create a stable output. This
  has been done because "`"thought up-to-date" compares the checked-in
  documentation to the documentation that would be generated right now.
  This requires the output of examples to be stable.
- Reduce load on traffic by executing Thought and Standard in their own
  build job (and not for each node version)
- Add caching-options to .travis.yml
- Run standard as precommit hook rathern than pre-push, because
  the check then always refers to the active branch.
- Run "standard --fix" on precommit rather than just "standard", because
  it is require most of the time, when "standard" fails.
