Linking Shell: use g_balance_pause_{health,armor}_rot cvars to stop health/armor rot (5 seconds)
Extended the Heal() function: supports armor healing, limits and heal types. Made most healing in the game pass through this function.
Fixed missing g_clanarena_start_shells cvar
Experimental showdamage setting: sv_showdamage_global - show damage/healing from other players. Not visible through walls by default (sv_showdamage_global_checklos)
Fixed negative VisualDamage for some non-player targets
Tweaked visibility for sv_showdamage_global
Fixed Heal() not working in ROUNDSTATE_WARMUP
Merge branch 'unstable' into vecxis
