[Polish project] Transfer data from 5.2 to master branch

Hi Mateusz, *,

I see there are suggestions in master, which I accept or cancel in 5.2. Is
it how it works?

Not sure what you you mean exactly. Maybe the same effect that was
already discussed here, mainly pootle taking exact matches from
translation memory and suggesting them as fuzzy? (making it appear
that there was a fuzzy string already present, but actually there was
no translation. You can tell whether this is the case if the entry
from the translation memory below the entry box is highlighted)

Apart from that: suggestions are pootle-internal/not exposed to the po
files, so no suggestions are copied over in the process.

I also did small bug corrections in 5.2 I was asked for by our users, but I
can't find them all in Internet. Once in Pootle I saw page with history of
translations. How can I track changes in my account?

Again you need to be more specific. To see the history of a string,
you'd click the timeline icon below the entry box. (the leftmost one,
that looks like a clockface/piechart)

ciao
Christian
