Default HIERARCH keywords with fmodhead of HEATOOLS

This is a patch of the Fortran program fmodhead in
the file ftools/futils/src/fmodhead/fmodhead.f of
the HEATOOLS http://heasarc.gsfc.nasa.gov/lheasof.../heatools.html :
to enable handling (adding/removing) HIERARCH keywords:

In fmodhead.f, line 243, the comment

C if extension is 0 then give error and exit

should read

C If extension is negative then give error and exit
C Allow fitsfile[0] to address the primary header.

In fmodhead.f, near line 208, add a variable
integer kylen

In fmodhead.f, line 210, extend the size of kywrd to 72

C Maximum size of keyword (including HIERARCH), equal to FLEN_KEYWORD
C in fitsio.h
character*72 kywrd

Replace line 275 in fmodhead.f (assignment of kywrd) by
C kywrd = card(1:8)
C Call a more general parser to deal with HIERARCH keywords
call ftgknm(card,kywrd,kylen,ftstat)

To install goto BUILD_DIR and recompile with
make install

Default HIERARCH keywords with fmodhead of HEATOOLS

A workaround for the problems of using fmodhead with HIERARCH keywords
is a re-implementation (based on CCfits) that I called fedithead, available
as www.mpia.de/~mathar/progs/fedithead.tar.gz . It uses the boost::regexp
package to allow block replacements, and ensures that the
keywords that are to be replaced and their new versions are
set apart by separating the two strings by colons.

From what I understand, sci.astro.fits is mostly abandoned
for being "obsolete" and active discussions are conducted via
fitsbits - which is a mailing list, of all things ...
