Mercenary, Regen and Frenzy Improvements (#8185)

- When a Mercenary gains a bonus, there will now be an animation
- Mercenary bonuses now last for 5 minutes instead of 10 minutes
- Fixed HP/SP recovery values of Mercenaries (and Elementals)
- Mercenaries now recover HP when walking
- Homunculi no longer recover SP when walking
- Mercenary natural recovery interval is 8s for HP and 6s for SP
- Homunculus natural recovery interval is 2s for HP and 4s for SP
- MER_CRASH now only deals 1 hit and can be cast-cancelled
- Frenzy now drains HP every 10 seconds instead of every 15 in pre-renewal
- Fixed SP cost Mercenary Frenzy (100 -> 200 SP)
- Killing monsters exactly 2 times below you base level now still counts as mercenary kill
- Fixes #8184 
- Fixes #7663
