Proto files can include other proto files. E.g. nanopb comes with a `nanopb.proto` include that contains some nanopb-specific extensions. This patch makes it possible to include this file as well as specifying additional proto include folders. I added the include to `simple.proto` so it gets exercised by the test.
Introduction
This is a test application for the nanoPb library. The library provides a Google Protocol Buffers encoder / decoder.

On Debian/ubuntu, the corresponding packages are protobuf-compiler and
python-protobuf. On Arch, it is protobuf and python-protobuf.
