Preparations for the login server TXT/SQL merge
- copied the sql login server code to /src/login - merged the login server header files - moved the account savefile name config setting to inter_athena.conf and renamed it to match the other settings git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12478 54d463be-8e91-2dee-dedb-b68131a5f0ec
