Add XML schema validation, split build scripts by module, rename BuyMenuCommand to PlaceOrderMenuCommand

Introduces XMLValidatorV1 and deserializer/adapter classes for events, ledgers,
markets, users, and trading mechanisms. Replaces the monolithic build.bat/run.sh
scripts with per-module tools (_util.sh, build.sh, package.sh, test.sh) that
compile in dependency order.
