- Added StringBuf_Vprintf to utils.c and changed the showmsg.c buffer.
Now it uses a static buffer and a StringBuf when needed (a debug message indicating the static buffer needs to be increased is shown). git-svn-id: https://svn.code.sf.net/p/rathena/svn/trunk@9414 54d463be-8e91-2dee-dedb-b68131a5f0ec
