Improve performance of distance calculations.

Moved distance() from MultiPolygonRelation class into Coord class to
form the basis of quickDistance().

Original distance() now renamed to slowDistance() and distance() now
calls quickDistance().

Added distanceInDegreesSquared() - this can be used for those situations
where absolute distance is not required, i.e. for determining a nearest
point out of a set of points.

Reworked Utils.toDegrees() and Utils.toRadians() to reduce number of
divisions at runtime.
