New way to read configuration tables:

(config_tables): New econfig key.
(read_config_tables): New, implements config_tables.
(main): Call it.  Need to call ef_init() and chdir(configdir) first.
(ef_init_srv): Don't call ef_init(), since main() did it already.

Remove old way to do the same:
(ef_load): Remove, along with calls.
(empfile): Set configuration tables' member file back to NULL.
