It is too easy to forget a ship in a hangar

Title says it all. Countless times I've wasted a few turns not using a ship because I did not realize it had just finish construction and was just waiting in a hangar somewhere. It's a bit silly. Surely I can't be the only one falling for this on a regular basis.

One way to fix this problem could be to consider a ship in a hangar as "inactive" for the purposes of the "select next inactive ship" button near the end turn button. That would provide a clear signal that there are ships that are sitting idle in hangars.
