Improvements to SelectTemplateDialog (#109 and #142)

- Added side pane for product preview and information
- Product selection is done with a separate pushbutton, so that user gets a
  chance to preview the complete product information before committing to the
  selection
- Supports two view modes: Grid View and List View
- View mode is automatically stored in Settings, so it will default to the
  user's prefered mode
- Should address most concerns in #109 and #142
