[addon] Paved roads

[Spike]

Roads can be paved an then the carriers can walk faster. To pave the street you need a roadworker who needs a hammer.

and a stone for each road-element?

Thumb up for this idea.
Paved Roads. Strictly speaking roads made of stone (Stone/Granite required). With paved roads settlers and donkeys would be able to move and transport goods faster than on normal or donkey roads. I suggests this kind of progress:
Normal road -> Donkey road -> Paved Road [However update to paved road should NOT be automatic]

Benefit:
- increase overall moevementspeed by 10% on those roads
- elimination movementspeed decrease when carriers move upwards (hills).

Costs:
For 2 road segments (means shortest road possible) you should need 1 stone, means for 3 segments, you
need 2 stones, for 4 also 2 stones etc. So travelling 1 node is effectly 1/2 stone.

The way they should be build, suggestion:
There should be taken 1 node of the road where next to the builder "waits" (like he doesn't have
enough resources for building). Both flags act as "building" flags. Means stones can
be brought to both. Now carriers just carry stone to those flags - they are placed
at the point where the builder is waiting. When all stones finally have arrived -
the road is closed, means everybode currently on that road can finish his way but
nobody can travel on that road while building. Flags may act like fighting soldiers.
Also while that road is under construction, we may place shields at the
beginning/end of that road. When the road is finished, it can be used by everybody again.
