Typo ListItem itemid in documentation

Dear Appcelerator,

we came across a small but significant typo @ http://docs.appcelerator.com/titanium/latest/#!/guide/ListViews-section-37521650_ListViews-ListDataItem

The ListItemData property 'itemId' is spelled 'itemid', which does not work, 'itemId' does.

Code Strong, best Wouter & Martin
