improved build system in Singuar/: building of libparse and [TE]Singular ADD/CHG: distribute and install emacs/ (under $(datadir)/) CHG: moved fegetopt.{c,h} from kernel/ to Singular/ ADD: build and install Singular/[TE]Singular ADD: better Singular/libparse CHG: only build the static release and debug binaries Singular&Singularg by default!
