Flight Computer status indicator

[Starstrider42]

It would be helpful if the flight computer icon would change to indicate the following two states:

• There are actions scheduled in the computer queue, or the computer is holding attitude.
• Manual delay is non-zero.

The second, in particular, is a very frustrating mistake to make ("Why isn't the ship responding to my commands? Why is the flight queue full of the action group I'm trying to use? Ohhh..."), so it should have a prominent icon.
