Disallow selecting text and images

[niccokunzmann]

To following I do not like:

The restart button can be selected. The start button can be selected.

This should be quite easy:

.noselect {
  -webkit-touch-callout: none; /* iOS Safari */
    -webkit-user-select: none; /* Safari */
     -khtml-user-select: none; /* Konqueror HTML */
       -moz-user-select: none; /* Firefox */
        -ms-user-select: none; /* Internet Explorer/Edge */
            user-select: none; /* Non-prefixed version, currently
                                  supported by Chrome and Opera */
}

I think a more appropriate fix would be to not use icon fonts and just display the icons as img or something like that. When I review all the pending issues I will consider you proposal and fix this issue one way or the other. Thanks.
