Update textproc/hunspell to 1.6.0

Can you check consumers (including non-default) for build regressions?

Minor updates affect SHLIB_VER which means adjusting LIB_DEPENDS, build glue (e.g. rP427160, rP427161, rP427163, rP427164, rP427165) and bumping PORTREVISION in consumers.

Make sure each _FILE is represented in LICENSE. Try testing with

$ LICENSES_ASK=1 make clean patch

@rakuco, is this change fine with you or do you want it in a separate patchfile?

[jbeich]

• Adjust CMake patches for libhunspell.so symlink but don't actually add it yet
• Wrap long lines in CMake patches
• textproc/kf5-sonnet: unbreak
• x11/kdelibs4: move hunspell-1.6 fix into a separate file

arc diff occasionally editing SUMMARY seems to be a black magic.

Sorry for not responding earlier, I was somewhat AFK. Glad to see it was committed.
