Add redirect feature for manually fine tuning the cursor's movement

Cursornavigation now has a property redirects, that allows defining
exceptions to the navigation behaviour. A redirect allows defining
a starting and an ending angle and a target object.
If the move command's direction falls between the limits, the algorithm
is bypassed and cursor is moved to the target object.
