Probably slipped through in the refactor: `getLinkStyle` was defined
in to places, was probably meant to live only in `Utils`.
In addition, it expected a `wrapper` expression which wasn't defined.
This commit fixes it by removing the second declaration of that function
and passing a third parameter to the one defined in `Utils`.
Introduced Style.svg() Style.png() Style.emoji() and
Style.icon() in Style.qml. Those should be used to
set the source in Images instead of using relative
paths. Usage:
Image {
source: Style.svg("check)
....
Also moved all Singletons inside a new "utils"
folder and made it a QML module, to use
import utils 1.0 instead of relative paths
Closes#3678
