* IDEMPIERE-5168 column AD_AuthorizationAccount.AccessToken is short on some case
- Allow reference Text with length 0 to be managed as CLOB/TEXT
- Increase AD_ChangeLog.OldValue/NewValue to 4000 to allow saving more information about changing long texts
- Change AD_AuthorizationAccount.AccessToken to CLOB/TEXT
- Change some important actual columns defined as Text Long, to Text with length 0 (this allows changelog, better 2Pack, encryption)
* Fix problem reported by Hiep Lq with Text/Text Long not shown correctly as encrypted
