LPS-49125

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-49125.

I updated the ```portlet-list``` margin (https://github.com/jonmak08/liferay-portal/commit/46a90368996709ad5246424f6eb352240bb97ee4) to make it match the margins from ```tree-item``` (https://github.com/liferay/liferay-portal/blob/master/portal-web/docroot/html/css/portal/tree.css#L28).  You can see the ```tree-item``` style from:
 
1. Go to Admin -> Pages
2. Click on a page in the tree
3. Click "Export" in the navbar

Please let me know if you have any questions.  Thanks!
