- Add new symbologies BARCODE_EAN8, BARCODE_EAN_2ADDON,

`BARCODE_EAN_5ADDON`, `BARCODE_EAN13`, `BARCODE_EAN8_CC` and
  `BARCODE_EAN13_CC` as replacements for `BARCODE_EANX`,
  `BARCODE_EANX_CHK` and `BARCODE_EANX_CC` and use in CLI/GUI
  (`BARCODE_EANX` etc. marked as legacy)
- For EAN/UPC accept space as alternative add-on separator to '+',
  and accept GTIN-13 format with & without 2-digit or 5-digit
  add-on (no separator)
- Buffer length of member `errtxt` in `zint_symbol` extended 100
  -> 160 (will be sufficient for eventual translation and
  gs1-syntax-dictionary errors hopefully)
- UPC-E: warn if first digit of 7 (or 8 if check digit given) not
  '0' or '1'
- manual: update for new EAN symbologies and mention EANX now
  legacy but still supported
