d3b-emu: reconstructing a Diablo III Beta server

d3b-emu reconstructs a server for Diablo III Beta client version 0.3.0.7447 in C# and .NET 8. Based on an earlier mooege version, it updates opcodes and message definitions and implements beta-era game systems, while Battle.net handling, item persistence and skill accuracy remain incomplete.
