Forge: Heavily improve the new automagical ASM transformers :D. Adds block place, sign update hooks. Adds simplified methods for verifying methods. It is ALL still done automatically (simplified signatures that are translated to obfuscated/real names @ runtime)

This also makes LWC for Forge load as soon as the server starts up so that most of LWC can load before the first ASM transformers are called (i.e. ItemStack for block place hook -- need access to Config stuff which needs access to the lib downloader, etc etc....)
