Merged the /loginmerge branch (topic:192754)

 * 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
