2403.2 Hotfix for Savegames

Thank you all for your very kind feedback!

• Save games now work flawlessly with the new control trees
• Windows are perfectly restored, including all anchoring/docking/spreading/alignment information!
• To support this: A new method .build() has been added to the control_tree to complete the builder-pattern. With that function, the control tree has all information it needs to restore a window after loading

Other changes

• InputBox will not receive focus after load, when it is not in the focussed window
• A small drawing/rendering bug in the checkable controls (RadioButton, CheckBox) has been fixed

Wiki update for the new function follows.

coldrock.games and raptor ui themes

• I've added two UiThemes to this release as yymps package. It's just two files, containing the coldrock and raptor standard colors, in case you are interested in the rgb values or when just want "another template" to see some more themes
• Those themes are also used in the demo project when you clone the repository

Have fun! Make Games!
Yours,
Gris
