Config V2

[neonphog]

• Does away with the ModConfig trait.
• We now just take anything Serializable for the set_module_config api.
• and can get anything that implements DeserializeOwned for the get_module_config api.
• Now supports runtime config alteration through register_entry_update_cb api.
• And adds some warnings for "this param may be unused" and "nobody's listening to this runtime update".

This is good, I like where it's going, just a few questions. Partly to make sure I'm following the code :)
