Set the initial task button text (and icon) correctly (#454)

Fixes https://github.com/lxde/lxqt/issues/1303.

Detailed explanation:

When a window shows up, the signal `KWindowSystem::stackingOrderChanged` is emitted *before* `KWindowSystem::windowAdded`. The former signal is connected to the function `LXQtTaskBar::refreshTaskList()`, which calls the functions `LXQtTaskBar::addWindow()` and `LXQtTaskBar::removeWindow()` to add and remove monitored windows.

Connecting `LXQtTaskBar::refreshTaskList()` to the signal `KWindowSystem::stackingOrderChanged` not only is redundant but also causes a problem:

(1) It's redundant because the job of adding *new* windows should be done by `LXQtTaskBar::onWindowAdded()` connected to the signal `KWindowSystem::windowAdded`. However, with the current code, `LXQtTaskBar::addWindow()` is never called by that function because the new window is already added through `KWindowSystem::stackingOrderChanged`. Similarly, `LXQtTaskBar::onWindowRemoved()` should be responsible for removing windows by being connected to the signal `KWindowSystem::windowRemoved`.

(2) More importantly, as the window name can change in the short interval between the emissions of `KWindowSystem::stackingOrderChanged` and `KWindowSystem::windowAdded`, the corresponding taskbar button may get a wrong text. The reason is that the signal `WindowSystem::windowChanged` announces changes only starting from the emission of `KWindowSystem::windowAdded`. (Theoretically, the initial icon might also be wrong but that's rarer).

Here, the connection to `KWindowSystem::stackingOrderChanged` is removed, so that the initial task button text/icon is set correctly. In this way, several useless calls to `LXQtTaskBar::refreshTaskList()` are also prevented when a window is shown/closed or focused/unfocused.

Drop Qt foreach

Replaced by the ranged-based for loop.
Qt 5.7.1 is required. We use qAsConst().
The replacement brings some performance improvements. Container detachments
and container anti-pattern use were fixed.
