Update project to new Xcode
Call the setter for cropToCircle instead of just setting the variable. Fixes #35
Remove setCropToCircle call in test project. Begin playing with setSelectionColor (issue #36) by setting to random colors
Added optional RSColorPickerViewDelegate methods for more detailed feedback during user interaction.
Replace variable with function call in assertions

Since the height variable is only used inside an NSAssert, and NSAsserts are disabled by default in Release builds, this change prevents four warnings (two standard, two static analysis) against a build.
