The layer names are not for logic control: when add/rename layer name, they can be duplicated and it doesn't affect the functions. Generally the layer name is just for organizing digitalizations, user can put any reasonable name even if (s)he choose duplicated names.

However it's not good for the default new layer name duplicated with those existing, so SWD and QA agree to fix "New Layer" function in this way: the default new layer name should be unique - there is no furthur requirement about how to define the name, for example, if existing name is "Digitizing layer 1", "Digitizing layer 2", the default name could be "Digitizing layer 0" or "Digitizing layer 3", as far as it's different from the existing.

Attach patch http://trac.osgeo.org/fusion/attachment/ticket/320/RedlineLayerName.patch for fixing.

Arthur, would you please review the patch? Thank you.

Reviewed. Please submit the code.

[Just a little suggestion: Can we use recursion to make the logic more clear.]
