Adds a version of template_ID that can be used for non-ID properties.
The property to search for and the collection to search in has to be
passed to it.
Like template_ID it also takes arguments to define a 'new' and 'unlink'
operator. They will be displayed as icon-only buttons then.
Also added a version that can display preview thumbnails.
Had to do some additional changes to make text-buttons support
displaying/modifying empty RNA properties.
This will be needed for workspaces, see D2451.

When layout has only small buttons (buttons with icon and without label)
its size should be fixed. Code was modified to be able to add a new UI_ITEM_MIN
flag which indicates that the layout has only small fixed-width buttons.
Patch by @raa, with minor style edits by @mont29.

Enum properties with icon only flag should use minimum/fixed width in expanded layouts (alignment=UI_LAYOUT_ALIGN_EXPAND).
Differential Revision: https://developer.blender.org/D2415 by @raa (only made some really minor corrections)
//ui_item_enum_expand// function replaces all pie menu's sub-layouts with radial layout. It should replace only root layout.
To reproduce the issue paste the code in Blender's text editor and press Run Script button.
```
import bpy
class VIEW3D_PIE_template(bpy.types.Menu):
bl_label = "Select Mode"
def draw(self, context):
layout = self.layout.menu_pie()
layout.column().prop(
context.scene.render.image_settings, "color_mode", expand=True)
def register():
bpy.utils.register_class(VIEW3D_PIE_template)
def unregister():
bpy.utils.unregister_class(VIEW3D_PIE_template)
if __name__ == "__main__":
register()
bpy.ops.wm.call_menu_pie(name="VIEW3D_PIE_template")
```
