Support building on Windows

Protoc should be in PATH and the project properties protobuf.include and protobuf.libs should be set. For example: gradlew build -Pprotobuf.include=C:\path\to\protobuf-3.0.0-alpha-2\src ^ -Pprotobuf.libs=C:\path\to\protobuf-3.0.0-alpha-2\vsprojects\Release When running more than once, it is probably more convenient to create %HOMEDRIVE%%HOMEPATH%\.gradle\gradle.properties with contents like: protobuf.include=C:\\path\\to\\protobuf-3.0.0-alpha-2\\src protobuf.libs=C:\\path\\to\\protobuf-3.0.0-alpha-2\\vsprojects\\Release
