It's possible to be ready and not be shown green in the coloured list of playernames

[Bluestone]

In fact this isn't a bug - it happens when:
(1) Player places a valid startpoint
(2) Player then places an invalid startpoint, which is rejected
(3) Player clicks ready without placing a second valid startpoint
In this case engine thinks player is confused; marks player as ready but not as green in list.

But player thinks it's a bug, because he still sees his first (valid) startpoint and thinks he clicked ready for it.

Solution is to reimplement list of coloured playernames to match how we use it (needs doing anyway because it gets too long). However ​http://springrts.com/mantis/view.php?id=4361 means this is not possible yet.
