Add naive color class/list

This will almost surely be removed for a better usage of the webcolors
code.
Add initial colors for specific units

Also added some dummy data to Archer class to allow it to run
Add archer group to defending units

Also disable Cassandra lines for now
Add fill property to units
Color archers yellow
Rename unitList to defendingList

Other name was too vague
Fix fill code in units
Fill defending units, draw outline of attackers

Also more failed lambda attempts. Apparently I'm an idiot for trying to
do assignments in them.
