Implemented glob-style matching for label selection. Introduces

Browse Source 
an optional extra argument to the "select" command that can be used
to select labels by glob-style matching;  e.g., "select area labels
VSS*" or "select less area labels *_1".  This will help in managing
labels after flattening a standard cell design;  e.g., by using
"select less area labels */VDD".
