WireGroup's get_names for different scopes

[yihuajack]

Previously get_name will regard all wires with the same name as the same wires, which is an oversimplification. Now, wire names are associated with their wire groups.

Can you check that the modified implementation of get_names works when __main__.py:169 is run? It seems to return a dict tree when it should return a flat list of names.

It is designed to return a dict because we want to construct a dict whose keys are scopes and values are sub-scopes or wire names.

I modified this function because a dict is needed for print_breakpoints, so get_wires returns a dict. To be consistent, get_names also returns a dict. The only reference of get_names currently is at Line 169 of __main__.py to raise an exception.

Therefore, currently the behavior of get_names does not make a difference. However, as mentioned In my report, if a better formatting of print_breakpoints is expected, get_names have to return a dict to distinguish different wires with the same names in different scopes.
