Forked Bintray.gradle from https://bitbucket.org/davidmc24/gradle-bintray-plugin/src/6adc1aca5ed712b8802fe6b3830b2d860d9fda88/Bintray.gradle as renamed to BintrayRepositoriesExtension.groovy. Initially this will just be part of the buildscript on this project, but the intent is to grow out to a full bintray plugin in its own right
Compilation achieved after added BintrayRepositoriesExtension. No tests yet, but as the code was imported, it is not quick TDD in a way. Need to figure out what to modify, and will then start by writing tests for the bintray Extension
Cleaned up gnumake/build.gradle
