…ditors

I can't see how to share a single set of index definitions between the
`dlgRoomExit` class and the `exitstreewidget` one - the latter is a base
class on which the former depends but getting the one to inherit from the
other is beyond me...

As it happens I spotted the need for the second set when I reviewed
`(void) ExitsTreeWidget::keyPressEvent(QKeyEvent*)` and spotted that I had
not revised it to close the correct persistent editors in PR Mudlet#439 seven
years ago!

…xits (#5505)

This will make changing/adding the columns easier as part of what was
created as the draft (and to be replaced) PR #5308 - that is to be broken
up into smaller, easier to digest, chunks! 8-)

There is a single set of constants which are defined in the `exitstreewidget`
class but used also by the `dlgRoomExit` one by virtue of making it a friend
of the former.

As it happens I spotted the need for both classes to have these constants
when I reviewed `(void) ExitsTreeWidget::keyPressEvent(QKeyEvent*)`
and spotted that I had not revised it to close the correct persistent editors
in the merge commit 83db9f9 (part of PR #439) seven years ago!

This will make changing/adding the columns easier as part of what was

Revised slightly (converted an empty switch "default:" case from a `;`
to a `{}`) to placate the CodeFactor god/daemon...!

…les (#6037)

This PR had three commits:
* The first commit just sorts in a case insensitive manner the files in the
OTHER_FILES and DISTFILES QMake variables. This is a precursor to making
changes to them.
* The second swaps some files between QMake OTHER_FILES and DISTFILES
variables. Technically the latter are for files that are needed to go into
a source tarball that the traditional GNU 'make dist' operation would
produce. As such it does not seem reasonable to include CI/CB control files
in it. Conversely the run-time LUA files that Mudlet needs definitely
should be included and so this commit moves them from the OTHER_FILES
variable, whose contents are merely files that we want to show up in the
Qt Creator IDE so they can be seen, searched and edited from there.
* The third changes the contents of QMake OTHER_FILES and DISTFILES
variables as there are files now in Mudlet that seem to have been forgotten
from being added to these variables so they can be seen in Qt Creator, they
are:
  * OTHER_FILES:
    * ./.devcontainer/Dockerfile (added by Setup Mudlet for C++ Github
