LPS-41929 - On a small mobile device, when adding content and viewing the permissions table, the column and row headers use character wrap and are hard to read

Hey @pat270,

Attached is an update for http://issues.liferay.com/browse/LPS-41929.  I made some changes to this, but it looks like the IE parts of it might not be what you had expected in your initial commit.  I did not like the 

```control-group { overflow: auto; }```

since it is so generic so I am trying to find another way to get the overflow to work.  Can you take a look and see if you can implement that another way?

Please let me know if you have any questions.  Thanks!
