Maven properties do not allow for limitation on artifacts

[wsargent]

When using the maven properties for milestone builds:

http://www.foundweekends.org/giter8/template.html#Maven+properties

The default.properties files looks in maven:

https://github.com/playframework/play-java-seed.g8/blob/master/src/main/g8/default.properties

description = This template generates a Play Java project
name = play-java-seed
organization=com.example
verbatim=*.css *.js *.png logback.xml gradle*
scala_version = 2.11.8
play_version=maven(com.typesafe.play, play_2.11)

but this comes out to 2.6.0-M1 because it picks up the milestone build. I'd like it to pick up only the 2.5.x branch, which is final.

Should be resolved with #275

I think we can close the issue, since PR #275 is merged. This PR change allows to specify stable branch in maven() call.
