Status icons for space objects

**What do you want to see?**
Status icons for space objects such as planets and ships. Some of these could be based on abilities, like the ruins icon, but others could be based on scriptable conditions such as being low on supplies. These icons could also be configured to appear only in certain locations, such as the system map and the ship list, and the script conditions and other configuration could be defined in a new data file, StatusIcons.txt. They could potentially replace the textual indicators on planets for things like space yards.

**How would it help players?**
Give the player the ability to see information at a glance, in a moddable fashion.

**Alternatives**
Just ability icons? A hardcoded list of icons?

**Screenshots and mockups**
N/A

**Things to consider**
Could all this client side script execution slow down the game? Might a cache be necessary?
