Do not download the protobuf source code automatically

[cesarbp]

Hello, I have a project https://github.com/bitemyapp/revise which depends on this library. I recently separated the compiled protocol buffers from the project into a separate jar (and dependency). And I also removed the plugin "lein-protobuf" from my project.clj (none of these changes are live yet) and then I deleted all of my .proto files.

My problem is that this still downloads protoc, compiles it and then downloads - a seemingly outdated 2.4.1 - protobuf jar. And in the end it does nothing because there are no .proto files to compile.

My understanding is that lein-protobuf should do the compilation while clojure-protobuf should just use the actual compiled protocol buffers. So what I want is that the user should be able to use them separately.

Also the automatic compilation of the protoc sources probably makes this project explode on windows.

Thanks.
