Fleet Carrier / System Mode

[jcc10]

This may be a bit odd or out of scope of the project, but it would be nice to have a mode for fleet carrier owners to use. Especially as EDCT is now archived. There would be a handful of features that would be helpful for this use case:

• System level trades; IE: mean rate of the good in given systems instead of calculating directly from stations.
• Multi-System trades; IE: how large of a cluster to monitor (if not a single system). Basically, used to let people hop from one system to another for larger trade windows.
• minimum / maximum jump ranges; IE: I have a carrier, any jump under 50ly is unlikely to make a profit, and my max jump is set at 400ly
• Max other carriers in source/dest system; IE: I don't want to be competing with more than x other carriers for the same goods.

I'd work on this myself, but right now I don't have my dev environment setup, and I also have not worked on a python project in quite some time.
