Initial commit of Guild Bot, as seen in:
$ sha256sum guildsrc.zip ef61469ab59ce3f5dd3289505e89bd5b84e3a82b89cda90d25ae3c41f7464beb guildsrc.zip Verification shown its source 100% match to currently running version on TMWA. The following changes were made VS version found in guildsrc.zip: 1) src/build and src/dist content completely removed. Rationale: build-time artifacts; binaries contained login/password. 2) Executable flag (+x) removed from src/automation.cpp and src/main.cpp. Rationale: executable CPP sources are weird thing. No change to file content. 3) src/main.cpp changes: 3 lines: std::string main_username = "test"; std::string main_pw = "test"; std::string main_host = "127.0.0.1"; Rationale: avoid leaking real production credentials and ensure experimenters dont hammer real TMW prod server by experiments. Effort been made to preserve original file timestamps, etc. However toplevel src/ dir date adjusted to date of mentioned changes.
