Issue with substituting recursive pom variables

[PiotrTrzpil]

Hi, the following build fails:

package cluster_service_build
import cbt._
class Build(val context: Context) extends BaseBuild {
  override def dependencies = (
    super.dependencies ++
    Resolver( mavenCentral, sonatypeReleases ).bind(
      "com.amazonaws" % "aws-java-sdk-s3" % "1.11.86"
    )
  )
}

Error:

Caused by: java.lang.IllegalArgumentException: named capturing group is missing trailing '}'
        at java.util.regex.Matcher.appendReplacement(Matcher.java:841)
        at scala.util.matching.Regex$Replacement$class.replace(Regex.scala:804)

        at cbt.BoundMavenDependency$$anonfun$lookup$1.apply(resolver.scala:400)

This happens when substituting pom variable: ${awsjavasdk.version}, because it's being replaced with another variable: ${project.version}, so a recursive substitution is needed.
