Make buttons disabled

This makes the button the disabled style if a <button> / <input> has the disabled tag in it.

reminder that this propose is kind of glitchy. I'm new to github so.. Anyways, heres the code:

.btn.disabled, .disabled.btn-large, .btn-floating.disabled, .btn-large.disabled, .btn:disabled, .btn-large:disabled, .btn-floating:disabled {
   background-color: #DFDFDF;
   box-shadow: none;
   color: #9F9F9F;
 }

.btn.disabled:hover, .disabled.btn-large:hover, .btn-floating.disabled:hover, .btn-large.disabled:hover, .btn[disabled]:hover, .btn-large[disabled]:hover, .btn-floating[disabled]:hover {
   background-color: #DFDFDF;
   color: #9F9F9F;
 }
