bug http://www.wowace.com/projects/ice-hud/tickets/13-low-health-colour/ - Low Health Colour

- added user-submitted ability to color a bar based on the low threshold. if it's above the threshold, the bar is max health/mana color, below the threshold is min health/mana color
- added a toggle to allow specifying whether or not to flash a bar when it falls below the low threshold
