* Added support for new delayed character deletion.

- Asks for birth date associated with the account and has a waiting time of 24 hours by default (setting).
- For SQL apply upgrade_svn14700.sql to upgrade table `char`; for TXT no action is necessary, as it upgrades itself.
- This completes support for clients 2010-08-03aRagexeRE and later.
* Updated login sql engine version, missed during `birthdate` addition (follow up to r14672).
