v0.16.0

Great Scott! It's a new Release!

To upgrade: yarn upgrade

Changes: v0.15.1..v0.16.0

Documentation: http://symfony.com/doc/current/frontend.html

Highlights:

• Added a priority argument to the addPlugin() method so that we
  can (mostly in the future) allow plugins to be ordered, if/when
  that becomes necessary - #177 via @Lyrkan

• Fixed several minor bugs related to extra .map files (#170),
  always having a DefinePlugin enabled (#172), fixing extra
  instances of the ts-loader (#181) and upgrading a dependency
  to avoid a deprecation warning (#182) - all via @Lyrkan
