Upgrade the dependencies used for adding dependency injection
annotations to Angular components and services, and the libs used for
code coverage reporting.

- Replace browserify-ngannotate with babel-plugin-angularjs-annotate.
  The repo's README states that the former is unmaintained and the
  latter is the successor.

- Replace browserify-istanbul + isparta + karma-coverage for code
  coverage reporting with babel-plugin-istanbul +
  karma-coverage-istanbul-reporter.

  babel-plugin-istanbul is the recommended method for instrumenting code
  using current versions of Istanbul. The karma-coverage reporter uses
  an old version of Istanbul. karma-coverage-istanbul-reporter is
  a reporter that uses the current version and is intended to be used
  alongside the Babel plugin.

- Upgrade karma and karma-browserify

This adds support for transpiling newer JS language features (ES2016+) and will
make it easier to update going forwards.

Decisions over what features to transpile for backwards compatibility
are controlled by browser coverage queries. See the browserslist docs [1] for
details of the query format.
