Subject: - Fixed #723 now it's possible to retrieve Battle Config Settings
 from plugins into scripts

- Fixed Possible Crash when null parse function pointer passed to HPMi->addConf
- Now it's possible to use same parse function for all config entries
- Now Battle Config entries must have a return function
