chessx: 1.6.0 -> 1.6.2

Source: https://sourceforge.net/projects/chessx/files/chessx/1.6.2/

Notes:

- Release 1.6.4 is the latest upstream release but it does not provide
a tgz source archive, so the application cannot be built from source.

- The official code repository (https://github.com/Isarhamster/chessx/)
  does not provide up-to-date release tags.

- Hence, only bump to 1.6.2.

- Previously applied patches have been removed, as they are now included
  in the upstream release.
