Fix self icontheme update (#113)

* lxqt-config-appearance: Update own icons on icon theme change event

The hack to do it was removed by commit lxde/lxqt-config@1cac4ae.
As the XdgIconLoader is the backend for all QIcon stuff (via lxqt-qtplugin)
we can simply use `QIcon::setThemeName()`.

Closes https://github.com/lxde/lxqt/issues/1220

* lxqt-config-appearance: Use const theme variable

A by-the-way commit.
