v0.3.0

• Changes
  • Favor singleton use of Delux with default arguments to render/3 and
    info/2. Now that Delux is being used more frequently as a singleton, this
    makes the API more convenient. This is backwards incompatible if you had
    been taking advantage of default arguments, but you should get compile-time
    and dialyzer errors. If you do name your Delux GenServers, you'll have to
    specify all arguments to render/3 and info/2.
  • Improve argument error messages by reporting what the valid options are in
    addition to what you passed.
