add flag for unlimited contract size

 * `--debug`: Output VM opcodes for debugging
 * `--mem`: Output ganache-cli memory usage statistics. This replaces normal output.
 * `--noVMErrorsOnRPCResponse`: Do not transmit transaction failures as RPC errors. Enable this flag for error reporting behaviour which is compatible with other clients such as geth and Parity.

Setting this to true **will** cause ganache-core to behave differently than production environments. (default: `false`; **ONLY** set to `true` during debugging).
