Labeling cities with icons

[tomaski]

DISCLAIMER: Feature first found in DIO tools, but since that script is abandoned, we decided to implement it.

Feature will add user selectable icons to visually group cities based on their function. Those function icons will be visible individually for each city (at city selector box) as well as a thumbnail on world map.

We're open for suggestions as to which labelling criteria you'd like us to include. Currently planning on:

• naval def
• naval off
• land def
• land off
• mythical def
• mythical off
• speed
• off
• def
• population
