Fix decorator reload crash.

- SetTopTap() -> SetTopTab().
- When reloading the decor, if the window in question is borderless,
short circuit. Previously, we wouldn't allocate a decorator for such
a window, but would then go through the remaining steps of attempting
to set the focus/top tab, which would obviously crash. Fixes #8500 and
possibly others.
- Add error check that adding tabs to the decorator actually succeeded.

Move flags and look into the tab too. The flags are needed to determine e.g. whether or not the zoom button should be drawn.

Set the top tab every time when adding a new tab. This draws newly stacked tabs correctly.

* Draw the complete decorator off screen and copy it to the front when finished. Stippi please take a look. This fixes some flickering when drawing shifted tabs in stack mode. In stack mode the different tabs sometime repaint each other, thus the decorator has to been drawn double buffered to avoid artefacts.
* Add an option to draw the button directly, i.e. when they are clicked.

Cleanup app server directory a bit by creating a font and a decorator sub folder.
