[Feature requestion] Add an option to toggle, in the editor, at the tab-bar of opened files, whether only the opened files are shown, or whether the additional four close-entries are also shown or not

[rubyFeedback]

There is another UI decision geany made that I would like to toggle,
in regards to showing the opened files.

If we click via the right mouse button, on any file that is currently
open (or rather, in the gtk-notebook tab bar with all opened
tabs), we get this right now:

a) a listing of all these currently opened files (via the short name
variant; as I mentioned in the other issue report, I'd prefer an option to
toggle the full name here, but that is a separate issue request)

and

b) additional options such as "Close All"

I can understand if other users find b) useful, but I find it totally
useless. I would not know why I would ever want to "Close All"; I
always re-arrange manually on a per-file basis. (I do use the Project
feature, so I am always working on ONE project, that is, all the
files I currently want to modify or that I may want to modify in the
near future. This is also similar how I used the old editor I abandoned
not long ago, which was gtk2 based. Here I was also working on a project,
so this is very familiar to me.)

I would thus like to propose a toggle-option here, one that specifically
allows us to ONLY show the currently opened files. This was also the
set-default of my old editor, so I am kind of used to that.

I tried to find an already existing option for this but failed to find
one, so I would propose a new entry in the preferences options,
possibly under "Editor -> Display", although I am not entirely sure it
belongs there. This toggle should have at the least two states - one
is the current default, let's call it:

"Display close options for the tab bar of the Editor [yes/no]"

And if no/false is selected then we only show the list of all files,
no other option there. So, "Open in New Window", and the four
"Close" entries there, would then not show up, thus only allowing
the user to see the files as-is.

I hope I was able to explain that feature request. Via a toggle option
people can decide which variant to use on their own; and the current
default remains the default, so people would have to specifically
enable this on their own, thus nobody has to change any of their own
behaviour as such.

Well if "somebody"¹ made a well implemented PR it might be accepted.
