Fixed bugreport:5788 WL_READING_SB should now work like official behavior(save preserved spell on relog, proper skill fail message, maximum number of spell that a char can hold)

Fixed bugreport:5657 WL_EARTHSTRAIN should now work like official behavior(total number of range [15x4+lv], layout when casted, interval)
Updated WL_IMPRISON duration, rate and proper skill fail message.
Special thanks to Yommy and his amazing tool...
