Community top navigation fix

[markknol]

Minor change, but at the moment the dots on community.haxe.org are displayed as blocks, and bit misaligned.

.brand.sub::before {
    content: "..";
    position: absolute;
    margin-left: -33px;
    margin-top: -23px; /* << move bit more to middle */
    line-height: 0px;
    font: bold 40px "Open Sans", serif; /* << serif font has round dots */
    letter-spacing: 0px;
    color: #f25c19;
}

These two changes will make it look like this

@ibilon I assigned you since I think you're the one that can do this, thanks!
