EXP on Max Level
* Fixed#942
* 'Last' EXP for max base level is 99,999,999 and 999,999,999 for Job EXP on max job level.
* Player still obtains EXP on max level (of course until both base & job reach 100%).
* This behavior is used for Base EXP check for:
* Super Novice's Explosion Spirit.
* Royal Guard's Inspiration.
* High Priest's Redemptio.
* Added config `death_penalty_maxlv`, default is set to 0. Player on max level, never loss EXP by death penalty.
* On EXP lost by death penalty. EXP will be shown as negative value.
* Fixed check for EXP value on packet `0x07f6`. EXP is limited to INT_MIN until INT_MAX by client (so don't expect client to displays value more than this!)
* Added EXP gained/lost message by `@showexp` on death penalty too.
* Fixed PR_REDEMPTIO and LG_INSPIRATION requirement …
* Only charge the Base EXP.
* Lost EXP will be displayed
