Rebellion Skills are added!
** Some attempts to support this job with its skills (as usable as good as I can, some of them are custom from limited info, maybe I miss some behaviors)
** Maybe some formulas, entries on skill_db, skill_require_db, skill_unit_db, and skill_cast_db are still custom
** Thank posters are on: (1) http://rathena.org/board/topic/85195-rebellion-class-released-on-kro-sakray/ (2) http://forums.irowiki.org/showthread.php?t=100131
** Some notes:
--> RL_RICHS_COIN, Rich's Coin
--> RL_MASS_SPIRAL, Mass Spiral: Bleeding chance and additional damage still custom formula
--> RL_BANISHING_BUSTER,Banishing Buster: Custom chance formula to remove buff/debuff
--> RL_B_TRAP,Bind Trap: Even I updated my client and use original lua, I stil can't see the trap
--> RL_FLICKER,Flicker
--> RL_S_STORM,Shatter Storm: Custom formula for success rate
--> RL_E_CHAIN,Eternal Chain
--> RL_QD_SHOT,Quick Draw Shot
--> RL_C_MARKER,Crimson Marker: Still doesn't show the icon of marked target on minimap (I don't know the packet for it)
--> RL_FIREDANCE,Fire Dance: Not sure it's only 1 hit damage or works like Desperado (I saw someone's screenshot, it seem only deals 1 hit)
--> RL_H_MINE,Howling Mine
--> RL_P_ALTER,Platinum Alter
--> RL_FALLEN_ANGEL,Fallen Angel
--> RL_R_TRIP,Round Trip
--> RL_FIRE_RAIN,Fire Rain: (1) This should able to remove ground target aroung its area, (2) And the splash area like a 'cone' (I imagined like someone uses gun then fire brutally to his/her front way)
--> RL_HEAT_BARREL,Heat Barrel: Still custom formula, but I saw the damage is increased highly.
--> RL_AM_BLAST,Anti-Material Blast: Custom formula for success chance
--> RL_SLUGSHOT,Slug Shot: Custom formula for damage (I saw someone's screenshot, bullet with 120 weight can deals 100k damage)
--> RL_HAMMER_OF_GOD,Hammer of God: If there is no enemy with SC_C_MARKER around the area, the skill Hammer of God animation won't displayed (maybe I missed something? I guess so)
(I guess some lines and algorithm should be cleaner, cooler, and sexier. :P)

IMPORTANT for client side:
- You should have up-to-date grf files
- I used original lua files, I didn't use translated lua files that exist nowadays because I think they need to update their supports for Rebellion
- Some items for Rebellion Skill's requirement(s) aren't added yet
