1.0.1

1.0.1

This is a bugfix release.
The API is stable enough and the code is being used in production, so the version is also being bumped to 1.0.0

• Fixed a bug wherein calling "Hocon.load" would not
  resolve substitutions.
• Fixed a circular dependency between the Hocon and Hocon::ConfigFactory
  namespaces. Using the Hocon::ConfigFactory class now requires you to
  use a require 'hocon/config_factory' instead of require hocon
• Add support for hashes with keyword keys
