#7 Show way of groups problem

[Chris Shaffer]

Show way of selected/all groups is color coded for
transports carrying cargo. The color coding only works
for ships which loaded cargo on the current turn. Ships
in transit from previous turns are not colored at all. Ships
that already had cargo (due to autounload being turned
off) are colored red (empty) even though they are
actually carrying COL or CAP or MAT.
