Split off mapreg code from script.c
* new mapserver files, mapreg.h, mapreg_txt.c, mapreg_sql.c * removed MAPREGSQL from project files / makefiles * mapreg storage engine is now fully dependent on the server type * added config settings mapreg_txt and mapreg_db to inter config * added get_str() function to complement add_str() * fixed txt mapreg code allowing too long variable names git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@13081 54d463be-8e91-2dee-dedb-b68131a5f0ec
