Significant diona and species flag changes.

- Dionaea will now move much more slowly when running and walking.
- NO_PAIN and IS_SLOW flags now exist for species (dionaea have both).
- NO_PAIN displays a permanent 100% health value on the HUD and prevents traumatic shock/paincrit. It also modifies several screaming emotes.
- IS_SLOW causes walking and running to be significantly handicapped.
- Fixes a whitelisting bug due to a duplicate flag definition.
- NO_BLOOD now functions. Mobs with the flag (vox and diona) cannot bleed out or have blood samples taken. Injecting them with blood will place it into their reagents.
