qqc2-desktop-style as framework

[Marco Martin]

Hi all,
we have a qtquickcontrols style that is right now in workspace (unrelased, to 
be released with Plasma 5.11)
it makes controls paint with qstyle to give it a reasonable desktop 
appearance, plus some fixes/workarounds to make qml a bit more desktop friendly 
(for instance fixes scrollwheel issues with Flickable)
sice it's pretty much untenable to make a desktop application with 
QtQuickControls2 without it and make it look anything near "native", so 
releasing it together plasma is probably not enough.
Applications using kirigami should be able to explicitly depend from it if 
they want, to require a native-looking look and feel on linux desktops (even 
on gnome would look already marginally better than with the stock "universal" 
or "material" styles)

it's a thing with no api, no libraries (not even an import, qqc2 styles work a 
bit differently), so as with kirigami only source compatibility on the qml-
side will matter

any objection into pulling it into a framework? anything particular for the 
procedure?
