update to transcalc-0.14

Changes since 0.13:

* Fixed multiline string problems in help.h which prevented
  compilation in gcc >3.2
* Moved build environment automake, autoheader, autoconf to a more
  modern version (autoconf support is for >2.50).
* Ported transcalc to gtk2.0, which means that the dependency on
  gdk-imlib is now gone. gtk2.0 included gdk-imlib natively.
* Corrected some minor bugs related to config file
* Changed speed of light symbol from C to C0
* Modified configure.in to work also with Mingw32 (and hopefully cygwin)
* Added fnmatch.c and fnmatch.h (needed for Win32)
* Added program version number to saved files
* Updated speed of light constant (!) and changed its name from C to C0
  to avoid clash with variables in other f iles. Updated vacuum dielectric constant
* Moved examples from src directory to a separate examples dir
* Clean-up most warnings during compilation
* Upon running for first time, $HOME/.transcalc dir will be
  created with config file and save file
* Units default values now saved in config file
* Upon exit, last transmission line values remembered in save file
* Made some slight changes in gui setup
* Added coupled microstrip image
* Update manpage
