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
