Empty gun for AI missions that do not need a gun.

Browse Source 
There is no "all but gun" RTB winchester option, so air to ground
missions with mixed weapon types will insist on using all of their
bullets after running out of missiles and bombs. Take away their bullets
so they don't strafe a Tor.

Exceptions are made for player flights and for airframes where the gun
is essential like the A-10 or warbirds.

* **[Flight Planner]** AI strike flight plans now include the correct target actions for building groups.
* **[Flight Planner]** Flight plans now include bullseye waypoints.
* **[Flight Planner]** Differentiated SEAD and SEAD escort. SEAD is tasked with suppressing the package target, SEAD escort is tasked with protecting the package from all SAMs along its route.
* **[Payloads]** AI flights for most air to ground mission types (CAS excluded) will have their guns emptied to prevent strafing fully armed and operational battle stations. Gun-reliant airframes like A-10s and warbirds will keep their bullets.
* **[Kneeboard]** ATC table overflow alleviated by wrapping long airfield names and splitting ATC frequency and channel into separate rows.
* **[UI]** Added new web based map UI. This is mostly functional but many of the old display options are a WIP. Revert to the old map with --old-map.
* **[UI]** Campaigns generated for an older or newer version of the game will now be marked as incompatible. They can still be played, but bugs may be present.
