This Pull Request lets users plan Tanker flights.
Features:
- Introduction of `Refueling` flight type.
- Tankers can be purchased at airbases and carriers.
- Tankers get planned by AI.
- Tankers are planned from airbases and at aircraft carriers.
- Tankers aim to be at high, fast, and 70 miles from the nearest threat.
(A10s won't be able to tank)
- Tankers racetrack orbit for one hour.
- Optional Tickbox to enable legacy tankers.
- S-3B Tanker added to factions.
- KC-130 MPRS added to factions.
- Kneeboard shows planned tankers, their tacans, and radios.
Limitations:
- AI doesn't know whether to plan probe and drogue or boom refueling
tankers.
- User can't choose tanker speed. Heavily loaded aircraft may have
trouble.
- User can't choose tanker altitude. A-10s will not make it to high
altitude.
Problems:
- Tanker callsigns do not increment, see attached image. (Investigated:
Need to use `FlyingType.callsign_dict`, instead of just
`FlyingType.callsign`. This seems like it might be significant work
to do.).
- Having a flight of two or more tankers only spawns one tanker.
- Let me know if you have a solution, or feel free to commit one.

DCS features a massive range of aircraft and land vehicles, and not all of them make their role(s) clear just from the name alone. What this commit does is add an "information" button (and resultant window) to the recruitment section. This should allow new players to understand what each unit is/does.
Current state - every aircraft has a country of origin and an introduction date for that variant. Some also have a small placeholder description, taken from ED's store page for that aircraft. There is also a placeholder picture (taken from a rejected image from my own personal photography) that will, in time, show a banner image of each unit.
Todo - add appropriate screenshots for each aircraft's banner, replace the placeholder text for each aircraft (this will take a while...) and add more data points for each unit type, such as a unit role (i.e. "air-superiority fighter", "multirole fighter", etc) or perhaps a list of weapons carried. I also haven't made a start on the huge number of ground units yet.
