Add render-related options to dataview sample

Browse Source 
To more easily expose problems add options to the dataview sample
related to rendering of items (applying mostly to the MyListModel page
only):

* Use left/centre/right alignment (Ctrl+1/2/3)
* Use top/centre/bottom alignment (Ctrl+4/5/6)
* Toggle tall row usage (Ctrl+7)
* Toggle keep on using small wx logo, regardless of row size (Ctrl+8)
* Toggle multi-line text usage (Ctrl+9)
