implemented automatic EOL translation support

 * activated via bit 4 of the ED flag (enabled by default)
 * automatic EOL guessing on file loading and translation to LFs.
   * works with files that have inconsistent EOL sequences.
 * automatic translation to original EOL sequences on file saving
   * works with inconsistent EOL sequences in the buffer.
     This should usually not happen if the file was read in with
     automatic EOL translation enabled.
 * also works with the EC and EG commands
 * performance is OK, depending on the file being translated.
   When reading files with UNIX EOLs, the overhead is minimal
   typically-sized files. For DOS EOLs the overhead is larger
   but still acceptable.
 * Return (line feed) is now an immediate editing command.
   This centralizes EOL sequence insertion.
   Later, other features like auto-indent could be added to
   the editing command.
 * get_eol() has been moved to main.cpp (now called
   get_eol_seq()
 * Warn if file ownership could not be preserved when
   saving files.
 * IOView has been almost completely rewritten based
   on GIOChannels. The EOL translation code is also in IOView.
