[BUG] rev927 BRC8 [Graphics] Graphics for ranged weapons

[Dado]

Hi Dan and team. I could not find anywhere that this is reported before so here goes:

1) the graphics for shooting arrows/ slings/ javelins and handguns does not appear on the screen (maybe it is not implemented yet in this build?)
2) the shooting arcs for ranged units are not there ( yes, i enabled them at the preferences screen)
3) the unit dots on the minimap are not showing.

1) no missile graphics
2) implemented, not enabled yet
3) fixed for revision 931
