1.2.20: fix #74 aar and cross versioning problems

fixed #74 by hacking off _ and anything that comes after it in module name
also remove overzealous exclusion of com.android.support:support-v*
 (support libs were never published to central under that groupId)
remove publishArtifact := false for sources (apklibs implicitly included
sources, aars do not)
