Skills: Slight Buff for Healthy Body

[MrFrank]

In addition to increasing the HP regen Eternal Soldier's Way of Vim provides by +1, it now boosts:

• Revenant's regeneration (provided at nighttime ticks by Strength of Darkness) by +1 (for a total of +11)
• Nexus Champion's regeneration (if Tattoo of Blood is purchased) by +1 (for a total of +2)

I know the HP regen for ES is a a function of Way of Vim, and the ES gets further regen boost by buying other skills in tandem with Way of Vim. My reasoning for the suggested change is the parity it brings, this way NC and Revs will get some of the benefit from Healthy Body as well. Well Revenants less so, but at least NC's Tattoo of Blood gets a little boost.
