Rallypoints should be rendered in player colors

[elexis]

As reported by cc, the rallypoints are always rendered in blue, but it would be more consistent if it would use color of the owner of the building.

The color is currently a property of the template, so it would have to be removed.

The changes have to be done in CCmpRallyPointRenderer.cpp. The player color can be fetched via cmpPlayer->GetColor() as in other C++ components.

I'll have a look. I now know the code.
