Update

I've been doing a lot of cleanup work and have slowly added a few new features, but it's mostly just steadfast avoidance of reworking the planet code, which is probably going to take several days of work to finish.

I have added a method for ships to detect when other ships are present to the game again. At one point I just generated a list in the Ship Actions area, but since I didn't want to have to implement a scroll bar if the list of ships was long, I decided to have a graphical proximity indicator that doubled as a link to take you to a new page that will show a list of ships that are present and give you options to attack or scan them.

Here's a screenshot of how it looks at the moment. I'm not completely happy with how it looks or the placement yet, so it will likely change several times before I settle on something.
