. Checkout of the "Define Web Content Forms" dialog

Browse Source 
- Scrollable list of registered Form Templates
 - Add to List feature to add selected form template to data list
 - Remove Form Template
 - Fist pass of Form Template Details page
. UISelectList component now support "rowIndex" property for single components rendered multiple times in a list
 - This allows command buttons etc. to be rendered multiple times but have access to the correct row data during event handling
. Minor UI tidy ups to UIData based tables with "no items"
. Some code cleanup, use of logger pattern
