Implement custom mark feature

Using:
Add that node in `actor_menu_item(_16).xml`:
```<cell_item_custom_mark x="1" y="1" width="24" height="16" stretch="1">
		<texture>ui_item_count_back</texture>
	</cell_item_custom_mark>```
In item's section:
```item_custom_mark = true
item_custom_mark_offset = -2.0, 0.0
item_custom_mark_size = 10, 10
item_custom_mark_texture = ui_item_count_back
item_custom_mark_clr = 100,250,100```
`item_custom_mark_offset`, `item_custom_mark_size`, `item_custom_mark_texture`, `item_custom_mark_clr` are an optional - will be used texture, size, and color from XML node. By default it has position at right-bottom of cell, remember about it on offset setting up
