Added link to VSCode-Proto3 extension in Other Utilities section

Update my projects' (DCCL / Goby) URLs.
Propose new extension for CGSN Mooring project.

Update options.md | fix website url for C# port of protocol buffers.. From `http://github.com/jskeet/dotnet-protobufs` to `https://github.com/jskeet/protobuf-csharp-port`

I have added the xsrpcj RPC implementation for java

Added Netifi Proteus to Registered Extensions

https://github.com/dcarp/protobuf-d is a conformance tested proto3
runtime library and code generator for D.

Add third-party RPC implementation: raster - a network framework supports pbrpc by 'service' keyword.

Add GDScript Protobuf implementation

Has support for protobuf v2.

Remove broken link to RPC implementation https://code.google.com/p/protorpc/. Going to this URL displays a 404 error message, with no indication that the project has a new location or still exists.

Add Awake Security's Haskell Protobuf and GRPC implementations

Add a link to my third party protobuf/gRPC implementation for GopherJS.

I added my project ProfaneDB, it is a database for Protocol Buffers objects. Written in C++, it uses gRPC as an interface for other languages.
It is still work in progress, but I'd love to get some feedback on it while I progress!

Github repo had moved, pointing to correct location.

* add Grpc Protobuf validation

Updated the location for `protobuf-maven-plugin`

Since the official home is looking like it will be in another repo, it makes
more sense for the relevant docs to live there instead.

Uses Google's C++ library for .proto parsing and uPB for protobuf
encoding/decoding; it supports both proto2 and proto3 syntax and
encoding/decoding is more than 10 times faster than pure-Perl
Google::ProtocolBuffers.

Add reference to Protocol Buffers Dynamic Schema (https://github.com/os72/protobuf-dynamic)

1.only support proto3
2.support oneof map
3.support nested message and enum for as3
