[xwiki-devs] [Vote] Use the Date Picker from AppWithinMinutes as the default picker for Date XClass properties

Here's the commit https://github.com/xwiki/xwiki-platform/commit/a6f4bd499fc2b1cf3757d423205a… . The main changes are: * Move the JS/CSS of the date picker used by AppWithinMinutes into the file system (/resources/uicomponents/widgets/datepicker). * Apply checkstyle to DateProperty and DateClass. * Modify DateClass to use the AWM date picker when the 'picker' meta property is set. * Add back the 'picker' meta property to Date property (in DateMetaClass) to allow developers to use a different picker than the default one (or no picker at all). * Use Boolean property for 'picker' and 'emptyIsToday' meta properties (was Number property). Since a Boolean property is stored as an integer property the only difference will be visually (checkbox instead of text input). I'd like to merge this into the platform. My +1. Thanks, Marius
