Add Scala and Scaloid support

[pocorall]

There are increasing demands on developing Android in Scala language. And Scaloid project also receives attention.

Please add Scala and Scaloid support.

An out-of-the-box template of a Scala project is here:

https://github.com/rohansingh/android-scala-test

And Scaloid can be enabled by just adding a dependency on that:

Nice project. We'll see how to support it as soon is possible. There is a lot of stuff in the roadmap.

@a-thomas @pocorall I've found this https://github.com/eed3si9n/treehugger - library for generating scala code. We need rewrite all project with this library for support scala 😄

[pocorall]

@mli-max Could you explain more about how treehugger is used for supporing Scala on androidkickstartr?

[rxqd]

@pocorall It has docs http://eed3si9n.com/treehugger/ It can generate classes, modules, methods and other scala code. I've not read docs yet, only looked out. In androidkickstartr they use similar library, but it's for java only
