Plug Updates

[slogsdon]

fixes #36.

Latest version of plug breaks routing/dispatching. The plug adapters are expecting just a conn returned, no {:ok, conn}. Plus, the router (which is acting as a plug) needs to have init/1 defined for initialization of the options.

Also updates the deprecated // to \\ to remove compile warning messages.

@slogsdon Change mix.exs to depend on elixir v0.12.3 if you change // to \\.

@ericmj I'll update the mix file here shortly. I had forgotten about it because of the latest version of plug requiring v0.12.4-dev.

[slogsdon]

Updated to reflect the Elxiir v012.4-dev requirement of Plug. Thanks for catching that, @ericmj.

Thanks @slogsdon . I need to pull this down and tweak the dispatch/controller code since it is still returning {:ok, conn}, i.e. when there's an error in the Controller. This is nice start though.

[slogsdon]

@chrismccord No problem. I thought I had caught all of the instances where {:ok, conn} was being returned. I can finish the changes if you haven't already started.

[chrismccord]

Please go ahead with the changes!

[slogsdon]

Pushed a fix to properly match on errors @chrismccord. Tests have been updated as well (sorry about not doing this in the first place) and are green.

[chrismccord]

Thank you!

[slogsdon]

No problem!
