Subject: Converted to proto2

This will let us use an older version of protobuf in Python, and allows
us to use the Godot protobuf implementation at all. Scalar fields with
custom defaults in data.proto were changed to not have a default,
because Godot doesn't handle it properly. The equivalent fields in
human.proto still have the defaults, and datapacker copies the default
value in if necessary. The Panel message in data.proto was also renamed
to PanelData because otherwise it conflicts with the native Godot class
named Panel. The double field in Letter was renamed to level2, because
Godot couldn't handle it well. Finally, common.proto was removed and
its contents were moved into data.proto, which allows us to generate
code for Python without needing to edit it.

NOTE: I had to slightly modify the Godot protobuf code generator. I'll
need to upload that somewhere.
