It should rather be in ui/

I've reverted my change to ui_lazy/dialog.css in my latest patchset. I can't
move it to ui/ because there's an existing dialog.css and they diverge a bit. 

I originally moved it to sources/ because it can't stay in ui_lazy. I can create
a separate CL to manually move it to sources/ or ui/ and rename it to
sources_dialog.css?

     this._input = this.contentElement.createChild('input');
     this._input.setAttribute('type', 'text');
     this._input.addEventListener('keydown', this._onKeyDown.bind(this), false);
 
     var addButton = this.contentElement.createChild('button');
     addButton.textContent = Common.UIString('Add');
     addButton.addEventListener('click', this._apply.bind(this), false);
