Breaking: #62925 - ExtJS Ext.ux.DateTimePicker removed

See forge#62925


The old ExtJS component Ext.ux.DateTimePicker has been removed and replaced with a bootstrap alternative. For technical reasons, the feature had to be removed. Thus the possibility to use "+3d" or "today" in input fields is no longer available.


Extensions which rely on Ext.ux.DateTimePicker will break.


Use the new bootstrap DateTimePicker component which can be loaded with require.js. Example implementations can be found in EXT:belog, EXT:scheduler and the FormEngine component of the TYPO3 CMS core.
