* the login server storage, ipban and logging systems have been abstracted and now provide a common interface; the rest has been merged into a single login server core (no more login/login_sql duplicity)
* storage systems are now added via compiler options (WITH_SQL / WITH_TXT)
* multiple storage engines can be compiled in at the same time, and the config option account.engine defines which one will be used.
* due to MySQL autoincrement limitations, accounts with id '0' will not be supported; account IDs from this point on should start from '1'.
* login_log() functions now again record IP addresses in dotted format, not as 4-byte integers (undo from r6868).
* removed config options that defined column names in the login table
* removed `memo` and `error message` columns from login db/savefile
* moved `loginlog` table to the logs database
* added sql files upgrade_svn12975.sql and upgrade_svn12975_log.sql
* due to changes to the login table layout, I added an !optional! sql file (upgrade_svn12975_view.sql) that will provide a certain degree of backwards compatibility with existing software; read the instructions inside carefully!
* moved third-party includes/libs to a separate directory
* updated project files / makefiles
Changed the way GM levels are handled
* removed conf/gm_account.txt
* added the gm level column to the txt savefile (after 'email' column)
* gm level information is now transferred along with account data
