Dynamic minimal size changing improved; works over layouts sharing alignment.
EnumContent sub-contents use EnumValueContent instead of BoolContent; fixes a few small bugs.
EnumContent substrings get translated (bug fixed).
The widget manager no longer attempts to set widget sizes smaller than their minimals, even though some will not be shown.
SwitchWidget: has fixed sizableness now.
