- date-widget does no longer set extension-data if readonly (not used and can conflict with other widgets using the same name, as it was the problem in PM)
- select-widget: fix for "can not unselect the last category"
- red error-messages have now a "white-space: nowrap" for nice formatting
- confirm-message did not quote single quotes (') correct, which caused the complete confirm dialog to fail and allways execute the button
- readonly textarea's without column and row specification are rendered now as <pre></pre> to only take space needed
- replaced extra am/pm radio buttons with single selectbox with times includeing am/pm (works much better with the existing layouts)
- fixed wired 12h clock: 12am,1am-11am,12pm,1pm-11pm (0-23h)
- added an select-hour widget to the select-widgets for the above
