"Close" window menu entry missing from View Browser window

[brickviking]

Describe the bug Opening a View Browser and checking the View menu doesn't show a "Close    Alt-F4" line at the bottom, though Alt-F4 closes the window fine.

To Reproduce Steps to reproduce the behaviour:

1. Open View Browser from the System Folder.
2. Click on View menu
3. Scroll down to bottom
4. No "Close Window" entry.

Expected behaviour A Close Window entry should be in the menu of all relevant windows, as Alt-F4 is a global keybinding honoured by all windows in Dolphin Smalltalk. I would normally argue for the use of Ctl-W but Alt-F4 has been around since at least Dolphin-4.

Screenshots If applicable, add screenshots to help explain your problem.

Please complete the following information):

• OS: 64-bit Fedora 28 Linux, 32-bit wine-6.10
• Dolphin: 7.1.20-10 but may be present in all Dolphins.

Items to think about

1. First, do the windows need to have Alt-F4 specifically mentioned in all cases where there is a relevant menu? The key shortcut is globally implemented.
2. If so, what needs to be edited? The resource_Default_View? If that's the case, that's a biggish job.
3. If a class needs to be modified (perhaps the relevant menu code for each window), how easy is it to do that? Should be easy.
