Sensory dulling/doc

• The Sensory Dulling bionic allows the user to negate the effects of pain, in a similar fashion to taking painkillers. Repeated use will make the character tired, however. Each use will generally remove about one 'level' of pain (e.g. Moderate to Minor pain).
• Having enough power at one's disposal allows this bionic to essentially render pain irrelevant, since it can rapidly removed. Until negative effects are introduced for sleepiness, this bionic, combined with Implanted Night Vision and Repair Nanobots can make sleep essentially pointless, since all forms of healing can be achieved by consuming power.
• In 0.D (Danny) this bionic removes the need for painkillers when installing other bionics, even while Sensory Dulling is deactivated.
