Polishing the UI

This version adds a visual notification to indicate the game being paused. Routine groups and weekly routines are now accessible directly from the Family panel. And the cycle of the year is presented visually, the current day is at the topmost point of the seasons wheel, and the wheel rotates as the days pass by. Hopefully this makes it easier to estimate when the winter comes or when the snow will be gone.

The weekly routine dialog now has proper summaries for all the routines. You can view them by clicking a routine caption in the legend section at the bottom of the dialog

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.
