const value for default in extension is not generated correctly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. protoc.exe extbug.proto -o extbug.pb
2. python nanopb_generator.py extbug.pb
3. observe extbug.pb.c

Orphan reference to  "foobar_struct_foobar_default" is generated without the 
actual const. This does not compile obviously.

Nanopb 0.2.6, windows 7, 64-bit

Please ignore the "lint-comments" on the generated .c-files, they are my own 
modifications.

Do you think it would be an acceptable fix to just remove the invalid 
reference, instead of actually supporting default values for extensions? That 
would require some additional initialization logic.

Once issue #79 is resolved, one can initialize the extension field easily to 
default value in user code.

I think the removal for invalid reference is valid fix for this at the moment. 
I guess the default-value support is quite a corner case.
