- Fixed hyphenation char limit.
 - Added handling of hyphenation for words len < 4.

 - Removed wrong z_ucs_rchar invocation, making refresh counts in
   cell-interface work again.
 - Added " to word separator chars.

 - Created separate function "get_path_for_locale" to get path for requested
   locale. This allows detection whether a locale is supported at all.
 - Adapted "create_locale_module" function to use "get_path_for_locale"
   function.

 - Added "get_interface_name" and "get_interface_version" prototypes for
   sound interface.

 - Added "i18n_libfizmo_INVALID_VALUE_P0S_FOR_PARAMETER_P1S" parameter.
 - Altered cell-interface error codes to allow new error message code
   "i18n_libfizmo_INVALID_VALUE_P0S_FOR_PARAMETER_P1S" to fit in line.
 - Added localized values for now parameter check error message.

 - Improved parsing of numbers for configuarion options (strtol instead
   of atoi for improved error detection and explicit false/true and
   yes/no checks).

 - Improved wordwrap to correctly process dashes in words by implementing
   a separate "word_start" index.

 - Added output of sound interface name and version for info command.

 - Made hyphenation skip the correct (TeX-defined) amount of letters at
   start and end of word.

 - Registered stream and abort function as soon as a new interface is
   registered. This fixes the output of error message while parsing
   configuration parameters.
 - Added output of error messages in case of problems during config
   parameters parsing.

 - Added libcellif.mk dependency to "all" target.
 - Fixed locale install to skip CVS directories.

 - Added test z-code in binary mode.
