[TIMOB-17617] iOS: Adding titleAttributes to Ti.UI.TableViewRow

This is more of a nice to have :) Instead of adding a Label within a TableViewRow, _(while crossing over the JSbridge into Native to create a Label & Row)_ is to have the possibility to have titleAttributes to the Row's title (see this for more on TableViewRow performance: http://docs.appcelerator.com/titanium/latest/#!/video/97758718 ??@10:37?? ). Ideally is to have the possibility to modify the *titleAttributes* of Rows as objects to be placed in an Array and then passed to the TableView's data: example:

var myRows = [ {title:'Programs', titleAttributes: {color:'blue', font: {fontFamily:'Snell Roundhand', fontSize:36} } },
               {title:'Another Row', titleAttributes: {... } },
               {title:'A Third Row', titleAttributes: {...} } ]
tableView.setData(myRows);

The above would be much more performant than creating a Label within a TableViewRow for each row.
