Status icons

[tylor]

Purely interface change. Probably good idea for addon too.
Add small icons in corner of creature sprites for specific ESPECIALLY important statuses and abilities. Rough list:

On others:
- Speed increase (numeric value)
- All kinds of damage reflection
- Sees you when you are invis/stealth
- All kinds of dispell abilities
- Spell Feedback
- Wildfire/Uttercold

On you:
- Impending Doom/Curse of Deat
- Martyr
- Reduced resistances
- Slow
