Update www/foswiki to 2.1.6?

[Doug Sampson]

Hello-

After upgrading to perl5-5.26.2, I keep getting perl-related errors each time I execute tools/mailnotify as follows:

root at aries:/usr/local/www/foswiki # ./tools/mailnotify
Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/(\%)(SEARCH){ <-- HERE / at /usr/local/www/foswiki/lib/Foswiki/Render.pm line 673.

The foswiki developers have told me that the version of foswiki newer than 2.1.3_1 have had these corrected.

Please consider this a request to upgrade the www/foswiki port to 2.1.6. Thank you.
