ICQ: Added patch from ryo-oh-ki:

 1. Compatibility fix for third-party local ICQ servers - ICQ Groupware and IserverD. Added new option in Network -> ICQ -> Account -> "[X] Legacy fix", it's off by default (wont connect to old ICQ servers).
 2. Compatibility fix for old non-unicode ICQ clients (crashes on file transfer).
 3. Fixed double-freed memory in oscar_filetransfer.cpp (crashes after file transfer).
