Namespaces are not respected

[tamird]

Hello! Thanks for maintaining this project. We're evaluating using this for our iOS apps and have run into a filename-collision issue, which seems to be caused by protobuf-swift not respecting package namespaces. Repro:

foo/person.proto:

package foo;

message Person {
 optional uint32 age = 1;
}

bar/person.proto:

package bar;

message Person {
 optional uint32 age = 1;
}

output:

~ protoc --plugin=../../protobuf-swift/src/compiler/protoc-gen-swift {foo,bar}/person.proto --swift_out=../../swift_protos
Person.pb.swift: Tried to write the same file twice.
~ echo $?

I am agree, but i don't know how do it task. In the swift and objective-c syntax has not "namespaces". I would think... Issue #27

Seems like you need a separate xcode target per package.

+1. I had to restructure my protobufs so all the messages were nested to avoid collisions. respecting the package would be huge.

You can test.
Branch name "package".

I have not finished. I should to clean up the code.
