no more 'crash dive blues'

[clive bradbury]

See my topic 'now we have a real submarine simulation'. Still testing , but this approach seems to resolve the 'crash dive blues'.

1. Initiate a crash dive.
2. Interrupt it, and your boat sits tail down (the blues).
3. Initiate an upwards depth change with the 'set_depth' command.
4. Hit 'maintain depth' ('A' key) and your boat levels out beautifully.
