3 bugs

3 bugs fixed in this release:

• #40: NPE when using all_fields_required (thanks @pavolloffay)
• #41: Enums not being generated correctly (thanks @tomarrell and @felixjung)
• #43: Nullable fields slipping through the cracks (thanks again @pavolloffay)

Option to generate schemas with JSON field names

Thanks @grant for your suggestion (#38), and also for tidying up the README file!

json_fieldnames is the new option (see README.md)

Targeted messages

A new feature by @schigh allows specific proto messages to be targeted (in case you don't want to generate them all). Thank you!

Fixing stack overflow with well-known google "value" type

Addressing #34

Supporting required fields

• Supporting proto2 required fields (thanks for your interest @YuanYingdong)
• Proto3 doesn't allow required fields, so we introduce a new flag (all_fields_required) which can mark ALL fields required

Option to prefix schema files with their package names

Added a new option flag prefix_schema_files_with_package which puts generated jsonschema files under a directory named for the proto package.

Supporting Google's timestamp proto

Timestamps will now be recognised as such, and schemas will be generated as an RFC 3339 timestamp string:
2006-01-02T15:04:05Z07:00

Warning when proto files have no package

We now emit a warning when a proto file has no package.

Handling some well-known types

• Handling some of Google's well-known types (thanks @mier85)
• Fixed links in the README (thanks @Fleker)

References, cyclic dependencies

• A huge PR from @wk8 (big thanks) which takes care of some long-standing issues
  • Cyclic dependencies
  • Correct handling of schema references
• Also removed the -u flag from the go get commands (in the Makefile and README)

This provides fixes for several historic issues.
