Added taper for inverted source time function (use switch TAPER_STF, see taper.c for definition) and individual time windowing (use switch TW_IND, then three columns are expected in PICK_FILE for each trace with picked time - twl plus - twl minus, in this case TWLENGTH_PLUS and TWLENGTH_MINUS are ignored). Time windowing is now also applied during the inversion of the source time function.

+  changed link to Mailinglist registration

char wm[1] should be wm[2], due to reusage of wm later on.
