Some todo list items so I don't forget them.

[dwomble]

1. Add carrier demand to the colonisation progress columns
2. Add move up/move down to the colonisation plan window menu to allow reordering
3. If the orbital and surface slot counts are available from Raven Colonial:
   • Add the counts to the bodies popup
   • Filter the Bodies dropdown based on base type and slot availability
   • Filter the base type dropdown based on the body and slot availability
4. Improve the bodies popup with more helpful information on the impact a given body will have on different base types
5. Use tkSheet to make the layout of the bodies data more visually appealing/easier to follow (used Treeview not tkSheet)
6. Clean up the carrier cargo handling
   • Track demand change to infer deliveries by third parties
   • Use recency of update to filter out of date CAPI results
   • Maybe redo the carrier window display with tkSheet
