Refresh the display more frequently.

changed the display refresh when performing long actions from every 15 in-game minutes (150 turns) to every 5 in-game minutes (50 turns). It just felt like it was taking much too long to refresh.

sleeping still refreshes every 30 minutes.

feedback on whether this is a bad idea would be appreciated.

i also updated a couple places to refresh the display before waiting – after selecting a book to read and after selecting a vehicle part to work on.
