Title: Allows for drawing of bezier curves in RMShape

Adds the following methods to RMShape:
```
- (void)addCurveToCoordinate:(CLLocationCoordinate2D)coordinate
controlCoordinate1:(CLLocationCoordinate2D)controlCoordinate1
controlCoordinate2:(CLLocationCoordinate2D)controlCoordinate2;

- (void)addQuadCurveToCoordinate:(CLLocationCoordinate2D)coordinate
controlCoordinate:(CLLocationCoordinate2D)controlCoordinate;

- (void)addCurveToProjectedPoint:(RMProjectedPoint)projectedPoint
controlProjectedPoint1:(RMProjectedPoint)controlProjectedPoint1
controlProjectedPoint2:(RMProjectedPoint)controlProjectedPoint2;

- (void)addQuadCurveToProjectedPoint:(RMProjectedPoint)projectedPoint
controlProjectedPoint:(RMProjectedPoint)controlProjectedPoint;
```
Mimicking the existing methods for adding lines and moving to points.
