Feature: consistent project names

[Andrei-Pozolotin]

1. motivation: sbt> eclipse produces short project names,
   which conflict with existing eclipse workspace projects with high probability:

2. solution: we suggest consistent project names with pattern based on project.id:

// Provide consistent project name pattern.
lazy val nameSettings = Seq(
  normalizedName := projectName(thisProject.value), // Maven <artifactId>
  name := s"Scala.native ${projectName(thisProject.value)}" // Maven <name>
)

// Generate project name from project id.
def projectName(project: sbt.ResolvedProject) : String = {
  convertCamelKebab(project.id)
}

// Convert "SomeName" to "some-name".
def convertCamelKebab(name: String) : String = {
  name.replaceAll( "([a-z])([A-Z]+)", "$1-$2" ).toLowerCase
}

3. for example:

• before

I think it might make more sense to enhance the sbt/sbteclipse plugin to add a prefix argument or setting rather than change Scala Native. This would be useful for anyone using Eclipse. Scala Native already publishes under org.scala-native and the artifact names need to be stable. If I am not missing something the names would change under this proposal thus making everyone change their build files.

1. thank you for the idea
2. this pr helps beyond eclipse
3. no, <artifactId> stays the same

Suggestion sounds good to me apart from the Scala.native. It should be Scala Native instead.

This changed the Manifest entries to "Scala Native nativelib" where they normally would be "nativelib" for example so the comment I had above was appropriate. See #1637
