Minimap as HUD element with API control
Features: * Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes() * New HUD elements for displaying minimap with custom size and placing * New minimap mode for displaying a texture instead of the map

-- Route programming system

--[[
Progamming routes:
1. Select "program new route" in the signalling dialog
-> route_start marker will appear to designate route-program mode
2. Do those actions in any order:
A. punch a TCB marker node to proceed route along this TCB. This will only work if
	this is actually a TCB bordering the current TS, and will place a
	route_set marker and shift to the next TS
B. right-click a turnout to switch it (no impact to route programming
C. punch a turnout (or some other passive component) to fix its state (toggle)
	for the route. A sprite telling "Route Fix" will show that fact.
3. To complete route setting, use the chat command '/at_program_route <route name>'.
	The last punched TCB will get a 'route end' marker
	The end of a route should be at another signal facing the same direction as the entrance signal,
	however this is not enforced and left up to the signal engineer (the programmer)
	
The route visualization will also be used to visualize routes after they have been programmed.

}
The first item in the TCB path (namely i=0) is always the start signal of this route,
so this is left out.
All subsequent entries, starting from 1, contain:
- all route locks of the segment on TS between the (i-1). and the i. TCB
- the next TCB signal describer in proceeding direction of the route.
'Terminal' once again repeats the "next" entry of the last route segment.
It is needed for distant signal aspect determination. If it is not set,
the distant signal aspect is determined as DANGER.
