This is used to provide a UI hint to guide players towards campaigns
that have been updated to work with the current version of the game.
All the campaigns we currently have were made for an unknown version of
the game, so they're all flagged as incompatible.
The version field is not the DCS Liberation version number because the
campaign format may change multiple times during development. Instead
the version number is a monotonically increasing integer that we
increment whenever a game change requires campaign updates.
* A Bluefor EWR 55GS in the campaign miz defines an optional EWR site. There is no distinction between how close or far it is to a base, so it's possible that there will be many EWRs within an airbase.
* A Redfor EWR 1L13 in the campaign miz defines a required EWR site.
It would be a good future idea to limit the amount of EWRs within a certain distance from an airbase. That way there's no chance of 5 EWRs all at the same airbase. Even better if there were something preventing any two EWRs from being right next to each other.
No campaigns take advantage of this yet.
Fixes https://github.com/Khopa/dcs_liberation/issues/524
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.
