znc: Update to 1.8.2

Changelog:
# ZNC 1.8.2 (2020-07-07)

## New
* Polish translation
* List names of translators in TRANSLATORS.md file in source, as this \ 
contribution isn't directly reflected in git log
* During --makeconf warn about listening on port 6697 too, not only about 6667

## Fixes
* webadmin: When confirming deletion of a network and selecting No, redirect to \ 
the edituser page instead of listusers page
* Make more client command results translateable, which were missed before
