#794 SMPlayer doesnt use icon from theme on Linux

[Ragnar Thomsen]

SMPlayer always uses the built-in icon in the upper-left corner of main window and also in the task switcher in KDE. E.g. the default KDE theme called Breeze has an icon for SMPlayer which doesnt get used.

I found that changing the line:
setWindowIcon( Images::icon("logo", 64) );
to:
setWindowIcon(QIcon::fromTheme("smplayer"));
in the file src/basegui.cpp fixes the issue.
