#100744 fix problems that occur if 5.0 update is done without first renaming node_type table by adding error messages and rerunning the core update that will fail, #100742 add escaping to sql, add UPGRADE.txt file

 - the original cck-bundled date.module is now outdated by Karen's date.module : http://drupal.org/project/date
(was removed from 4.7 branch some time ago)

 it

(+ fix title label not appearing - my fault...)

 on node display

+ small code reorg

when changing storage from 'per field' to 'per content type', NULL values were copied as 0 or string 'NULL'

Add drop table and clear cache to install after moving files from node_type_content table to core node_type table

unifying how single and multiple field stores empty field (store 0) - hopefully the last fix for this noderef series, sorry for the back and forth dance

Now that content type delete hook is implemented in core, need a slight fix to cck handling of deletion to make sure field table exists before trying to delete it.
