* Merge all three comm_order arrays
Were Comm_orders, Sexp_comm_orders, and Player_orders. Now all Player_orders.
* Fix Warnings
* Fix erroneous order warning
* Update Int3 into a warning
* Fix missing location for warning
* Allow Fred to Edit and Allow Command briefs in FRED
They are currently allowed in the game, but not being allowed in Fred was an oversight of mine.
* Allow Command brief saving in qtFRED
Add FRED comments. These aren't the typical source-code style comments that are embedded in mission or table files; these are regular strings that are stored as mission data. You might think of them as annotations. Right-click on any node in the event tree and click on Edit Comment to add one. The tree node will then show a different icon and the comment will be visible as a tooltip when you mouse over the node text.
For quite some time missions have had the ability to edit more than one background. This was previously used for fallback loading in case the first background's bitmaps were not available, but I realized it would be very handy to allow switching between backgrounds for in-mission jumps.
The FRED background dialog can now add and remove backgrounds from the list. Additionally, a new `change-background` sexp can instantly switch between backgrounds without messing around with bitmap references.
This adds the titular feature, as well as FRED support. There are also some associated minor UI fixes in FRED and some cleanup in missiongoals.cpp. And "Event Flags" are now a thing in case we want to add any other flags in the future.
This adds a new AI goal which is equivalent to play-dead except that it "sticks". It doesn't clear the goal list
so it will continue playing dead until the goal is removed or another goal with a higher priority is added.
This adds a mission file option for ships which allows specifying a
different string which should be used for displaying the name of the
ship to the user. This name will not be used in SEXPs or other ship
lookup functions so it can be freely translated and two ships can also
have the same display name.
The new feature can be used by adding $Display name: <string> after $Name
for a ship in a mission file. I think I added proper support for FRED
(and qtFRED) so that this new value is properly saved but it would be
great if someone could test that.
This implements one of the features requested in #1730.
