In #4875 we changed the comparing between users to be locale-unaware.
During this change, the sorting was made case-sensitive, whereas before
it (potentially) was not.
However, intuitively a user will expect a case-insensitive ordering of
users in the UI. The only problem with that is that a case-insensitive
comparison will not yield a strong ordering between users that use
usernames that only differ in casing (e.g. "tom" and "Tom").
In order to avoid this problem, we now first perform a case-insensitive
comparison and fall back to a case-sensitive one, should the first
comparison yield "equal".

Apparently the first commit (59ae429972)
did not include all files.
Furthermore the used script tended to produce funny results in certain
cases. This has been fixed and as a result thereof a few more changes
were made in this second run.
If two persons are reading out the users in a channel in the order they
are rendered, chances are that they will read the names in a different
order. This is because the ordering of users takes the currently used
locale into account that can differ from machine to machine.
This is an inconsistency that one probably does not expect.
Therefore this commit changes back to using a lexicographical comparison
that should be the same on all machines, regardless of the locale.
Fixes#4873
According to Qt's documentation the PCH header doesn't need to be included.
From https://doc.qt.io/qt-5/qmake-precompiledheaders.html:
"To make your project use precompiled headers, you only need to define the PRECOMPILED_HEADER variable in your project file."
"qmake will handle the rest, to ensure the creation and use of the precompiled header file. You do not need to include the precompiled header file in HEADERS, as qmake will do this if the configuration supports precompiled headers."
