Subject: [PATCH] [API] Add customisation of reroute bezier controls (#846)

Allows globally setting the bezier control point offset from the reroute
centre point. This can be increased to allow larger curves on longer
links, or set to 0 to completely disable the spline on inter-reroute
link segments.
