+# Arguments:
+# 1: Whether to add or delete the shortcut from the desktop.
+#    'nej' or 'falsk' removes it.
+# 2: The name the button should have on the desktop. 
+#    If you choose deletion, the contents of the name argument does not matter.
+# 3: Whether to prompt for restart or not
+# 4: The icon to use for the button. Ideally SVG, but PNG works as well.
+#    If you choose deletion, which file you add here doesn't matter.
