Polishing the UI

Full change log:

• ADDED: A routines button to the family UI panel, to show the weekly routines dialog.
• IMPROVED: The weekly routines dialog now allows switching between existing groups, and adding members to the chosen group.
• IMPROVED: At the bottom part of the weekly routine dialog there are the routine items in different colors. Clicking each item brings up a summary for that routine, usually about how the hours have been spent for the week. But, for some of them it only showed a plain todo message. All of the missing summaries are now implemented.
• ADDED: A groups button to the family UI panel. That opens the routine group management screen, which allows adding and removing groups and assigning members to the groups.
• IMPROVED: The routine group management dialog got its UI upgraded, hopefully making it now more intuitive to use.
• IMPROVED: There was occasional confusion with handling automatic / manual / forced game pause and resume. This should be better now.
• ADDED: A visual presentation showing the current date related to the cycle of the year and changing of seasons. This is visualized with a sphere showing round color and a broadleaved tree wearing their seasonal colors.
• ADDED: When game is paused a HUD panel is shown on top of the map. The panel can be dragged around. If clicked, it will resume the game.
• CHANGED: Reworked the arrow indicating if new tasks will go to the left or right end of the queue of planned tasks.
• FIXED: Some seemingly random crashes which were related to the AI running another family unit in the background.
