Implement new Transform API

[williamwebb]

Issue #101

[williamwebb]

Don't merge this. Broken for Library Projects. Investigating...

[Turbo87]

@JakeWharton could you have a look at this fantastic contribution and possibly merge it?

[Turbo87]

FWIW I've packaged this branch up and it's available for public use at https://jitpack.io/#Turbo87/hugo/1.2.2

I've also just tested this on a mixed Java and Kotlin Android app and it seems to work quite well. Good job @williamwebb!

I couldn't get it to work. Please provide specific instructions.

@Turbo87 would be great if you could provide us with more information on how to use this. Removed apply plugin ... and replaced it with your jitpack implementation, but gradle fails.

@guidedways I could get it to work with

buildscript { 
    repositories {
	...
	maven { url 'https://jitpack.io' }
   }
    classpath `com.github.Turbo87.hugo:hugo-plugin:1.2.2`
}

and apply plugin com.jakewharton.hugo
