Changes Small bugfixes when importing old databases New trait time estimates. Earlier the estimates were showed how often the trait would be executed if no constraints applied at all. Now additionally an estimate based on the standard calculations is given for all traits that are used in the predefined households. It still needs work, but should already be a large improvement. Added an area to the modular household screen to show an estimate of how well-defined a person is.
