There is a bunch of text messages in Extension:UploadWizard that
deal with putting uploaded files into Categories of the wiki.

They are worded in a way as if categories were added to files.

This wording is wrong and bewildering, since files actually are
being put into categories - while category links, or category
references are being insterted into the description pages of
files.

It is impractical to translate "put a categoy into a file" since
that may incorrectly suggest the file's data was being altered,
and putting a category into its content was as strange as
"pouring a jar into lemonade."

Besides that, the current wording appears extremely misguiding
to me. Users should be educated to understand how putting stuff
into categories technically works. Once they start editing
description pages, they will have to understand and know it.
