[GiNaC-devel] Add methods constant::get_name

Dear All, Following the suggestion https://lists.ginac.de/archives/list/ginac-list@ginac.de/thread/6HSODYN2NJTI... and implementing the existing policy "constants behave pretty much like symbols" I am attaching a micro patch adding constant::get_name() and constant::get_TeX_name() methods.
