Inspect character

See #10
"Inspecting" a character/player will open a window where detailed information about the selected player will be displayed.
This will include:
1. Their name
2. Their preferred body type (gender/sex)
3. Their current class and the level of the class
4. Current and maximum health and mana values
5. Equipped weapon

Preferred body type is currently not implemented. Just add placeholder for now.
