Show mine timer in Highlander games

What problem are you currently facing?
The mine timer is not shown in Highlander games, but the game scheme editor can 
be used to change it.

How do you think the situation should be improved?
By showing the mine timer in the mission "window".

What version of the product are you using? On what operating system?
0.9.21 on GNU/Linux.

Don't forget that patches are welcome ;)
