In several cases we don't want menu(s) to close when an action on menu was
done. For example on drag-n-drop or menu item deletion (where confirmation
dialog is shown).
In such situations `s_bPreventClosing` was set to true (and then back to
false when closing was allowed again).
Though original code honored this variable only in certain situations and
typically (at least on Win10) menus were hidden/closed despite of it.
This patch changes the behavior and menus(s) are not closed when
`s_bPreventClosing` is set to true.
Basically now menu(s) stay visible until there is an action that changes
active window.
Following functionality was also removed because it is not needed now:
* CMenuContainer::HideTemp
* COwnerWindow::OnClear
WM_CLEAR was sent to the window only by already removed `HideTemp`
`Open-Shell` needs to adjust itself after OS upgrade. It seems that
`StartMenuHelper` registration is lost after such upgrade:

To fix this registration, administrator rights are required (means user
interaction, UAC).
While this is acceptable in consumer environment, it is typically not
desired in business environment where users typically doesn't have
administrator rights.
This patch allows to run `Open-Shell` in silent upgrade mode that will:
* check if OS version changed (otherwise end immediately)
* perform OS upgrade tasks without any user interraction
Such mode can be then used to create scheduled task that will run this
silent upgrade check on every boot with system rights:
`schtasks /Create /RU "NT AUTHORITY\SYSTEM" /SC ONSTART /TN "Open-Shell OS updgrade check" /TR "%ProgramFiles%\Open-Shell\StartMenu.exe -upgrade -silent"`
#167
Commit 1a5f62a added possibility to hide Lock/Sleep/Hibernate buttons if
they were disabled in system power settings.
Unfortunately this didn't work for Lock button.
To fix the behavior we have to add lock command to `g_StdOptions` array
and then all the checks introduced in 1a5f62a will apply properly.
#173
Latest version of ClassicShell was 4.3.1. There is no reason to display
any warning about very old versions (< 2.0.0).
Besides, this will remove dependency on version.dll which could be misused
for DLL hijacking attack.
Fixes#72
* Fix naming inconsistencies
'Menu' vs 'StartMenu'
* Installer: Remove Facebook link
* Installer: Remove PayPal donate remnants
* OpenShellReadme: Remove info about product version
