Bio Shield Antics :P

- Bioshield glow is less intense than before. Should be less annoying on the eyes now. >.>
- Lisa can now charge her bio-shield when it's turned on by pressing [Strafe Left + Strafe Right - Use/Open] in combination. It recharges at 3 ES points per 1 EP per tick, or 8 ES per 1 EP when the shield's advancement level is upgraded.
- New Sound for the bio shield fully charging.
- Keys legend in the upper left corner now uses color coding for the keys themselves. I plan to likely adapt this to future legends like the main menu's for example. >.>
