Readded the scroll bar missing segment.

Can be seen when playing the oldTest map in the objectives window.
Made the horizontal pipe go under the minimap frame and not stop abruptly anymore.
Colored the horizontal pipe seen while playing to the seat color.

This will hint on the player's current team while playing.
Normalized the sounds that needed to be.

This should help with the noise heard on linux according to the SFML bug
with floating point audio.

I also let only one claim tile sound, since they were all the same one
with a small change in volume that couldn't be heard anyway.
Part of #148

Made the Objectives complete message on top of the objective list.
Made the failed objectives listed first, too.

Added a chat message when winning.
