Not enough TU to reload

[zatarra86]

This is very trivial, but I suggest that when you try to reload and get a 'Not enough time units' message, that the ammo (rocket, clip etc.) should automatically 'put itself back' in its slot/pocket.

'R' key in battlescape reloads instantly without needing to use the inventory. All automatic at the push of a button!
