Remove conversion from counterrev implants.

[Ikea]

Being converted heals and also deaths and bloodshed are good for a gamemode like revs.

Being converted itself does not heal. The loyalty heals and if there is incentive to beat them down then it is likely people will outdamage the loyalty implant, frankly I'll even admit myself I tend to just leave revs dying on the floor after unrevving them because there isn't time to fix them.

Converting by significant usage of percussive maintence does heal you up to 30% hp. I had the idea of a brief 3 second or so effect that gave you increased melee prot just to give people a bit of time to realize oh they converted time to stop hitting em, but that would be a change separate to the one discussed here.
