Added custom battle config support

You can now define custom battle config structure members in src/custom/battle_config_struct.inc and initialize them in src/custom/battle_config_init.inc
You can put the configuration into any battle configuration file, but we recommend you to put it into conf/import/battle_conf.txt

src/custom/battle_config_init.inc
