Reference Bintray packages without "-mod" extension

[mohlemeyer]

Currently, for the reference from the module registry to a Bintray package to work, the uploaded file on Bintray has to have the form

{module_name}-{version}-mod.zip

although the module identifier is

{owner}~{module_name}~{version}

It is expected to be able to start/include a module by module identifier, e.g.

vertx runmod {owner}~{module_name}~{version}

which is currently not possible. Instead one would have to append "-mod", as in

vertx runmod {owner}~{module_name}~{version}-mod
