[Radiant] my css for the bucket

[eiked]

While we are at it,

I added some css to the assets module to make it work for me.

public/stylesheets/admin/overrides.css


#show-bucket {
    float:right;
}
#show-bucket a {
    display: block;
    text-decoration: none;
    margin: 0px;
    padding: 2px 5px;
    border: 1px solid rgb(0, 92, 157);
    background: white;
}
#asset-bucket {
    z-index:20;
}
