Spot Correct cleanups/additions

Suggestions from @Klaus Cinibulk

A) I like the clone brush! When setting the source I’d like to see the mouse cursor change its shape immediately (like it’s done in Photoshop for example). Like, Pressing Option immediately changes to crosshair as long as the Option key is pressed.

C)

Another idea for the clone brush would be to give it the same properties as the retouch brush, i.e. Strength, Feather. Aren’t the clone and retouch brushes very similar, except for the clone source?

D)

Shouldn’t here be a keyboard shortcut for Spot Correct?

E)

In the Keyboard Shortcuts editor the parameters for “Brush edge” should be re-named to “Feather” or vice versa, just to be sure that both refer to the same property.
