Fixes and Updates to spell and melee mitigation runes.

Browse Source 
-Fix for calculation error when rune was to be removed.
-Updated to support these spell effect limit values which
give a max amount per hit/spell that can be mitigated.
-Updated to allow support for these spells effects when
the max (rune value) is set to zero, which essentially
gives you unlimited mitigation but typically there is
a limit value set.
