Missed new files for new Date Field module.
Start creation of new date_field module to take the place of the old date module
Remove datetime and datestamp field types, eliminate date_default_format function
Start process of removing all storage types except ISO to simplify the code.
Major refactoring begins to adapt to the stuff I hope will move into core. Removing Date Popup module which is basically handled by core patch. Removing the text widget to simplify things. Lots more coming.
Update Date to use Formatter and Typed Data plugins.
Remove date_default_timezone() function and replace with drupal_get_user_timezone().
Move date_granularity_names() into DateGranularity class
Remove unneeded date_timezone_is_valid() function. Used only in one place which can do this directly.
Remove unused date_timezone_abbr function.
