Fixed #122 @accountinfo issue
* Now inter-server always asking to login-server for account info instead using direct query to `login` table. Merged from HerculesWS/Hercules@da233d5
* Inter-server packet usage: HA 0x2720 & AH 0x2721
* Additional changes from inter-server to map-server to parse the account info result with type 1 by using packet 0x3808 for clif_account_name(). Just some changes from @lighta at his old diff
* Moved some messages to char_msg.conf
* Updated inter-server packet documentation
