Switch Button more intuitive

Hi @fclaussen,

I propose this basis code to customize switch button with dashicons-controls-play and dashicons-controls-pause included, what do you think?

Red when OFF, green when ON.

CSS:

    .onoffswitch {
        position: relative; width: 65px;
        -webkit-user-select:none; -moz-user-select:none; -ms-user-select: none;
    }
    .onoffswitch-checkbox {
        display: none;
    }
    .onoffswitch-label {
        display: block; overflow: hidden; cursor: pointer;
        border: 2px solid #FBFBFB; border-radius: 20px;
    }
    .onoffswitch-inner {
        display: block; width: 200%; margin-left: -100%;
        transition: margin 0.3s ease-in 0s;
    }
    .onoffswitch-inner:before, .onoffswitch-inner:after {
        display: block; float: left; width: 50%; height: 28px; padding: 0; line-height: 28px;
        font-size: 34px; color: white; font-family: Trebuchet, Arial, sans-serif; font-weight: bold;
        box-sizing: border-box;
    }
    .onoffswitch-inner:before {
	font-family: 'dashicons';
	content: "\f523";
        padding-left: 10px;
        background-color: #4DDB0B; color: #FBFBFB;
    }
    .onoffswitch-inner:after {
	font-family: 'dashicons';
	content: "\f522";
        padding-right: 10px;
        background-color: #FB1B1B; color: #FBFBFB;
        text-align: right;
    }
    .onoffswitch-switch {
        display: block; width: 18px; margin: 5px;
        background: #FBFBFB;
        position: absolute; top: 0; bottom: 0;
        right: 33px;
        border: 2px solid #FBFBFB; border-radius: 20px;
        transition: all 0.3s ease-in 0s; 
    }
    .onoffswitch-checkbox:checked + .onoffswitch-label .onoffswitch-inner {
        margin-left: 0;
    }
    .onoffswitch-checkbox:checked + .onoffswitch-label .onoffswitch-switch {
        right: 0px; 
    }

HTML:

    <div class="onoffswitch">
        <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch" checked>
        <label class="onoffswitch-label" for="myonoffswitch">
            <span class="onoffswitch-inner"></span>
            <span class="onoffswitch-switch"></span>
        </label>
    </div>

I also propose to replace the blue color of the plugin by a more neutral color because the blue is not necessarily appropriate with the colors of all sites.
