Implemented (EXT-4705) Show maturity icon on Region/Estate tab.

- Added LLIconsComboBox class - a combobox with icons for maturity ratings.
- Fixed scroll list maximum width calculation. The width was calculated based on text value width for non-text columns.
- Added image overlay alignment getter method to LLButton.
