Add support for building projects with SBT and Maven

[rtfpessoa]

@PCManticore @machadoit just moved the builders to this project.

Cool, thanks! Just curious: it's just a move or you modified any code?

[rtfpessoa]

I did one fix. I am doing 2 different commits at the moment.

Yeah it makes sense here, merge when you split into 2 commits

@PCManticore just commited. If there was no scala- directory it would create a weird path.

fyi, regarding paths, you should concatenate them with Paths or File apis.

import java.nio.file.Paths
val basePath = Paths.get("/tmp/my/path")
basePath.resolve("mySubDir")                  /tmp/my/path/mySubDir

import java.io.File
new File("/tmp/my/path")                      /tmp/my/path
new File("/tmp/my/path", "mySubDir")          /tmp/my/path/mySubDir
