open_plugins add name when plugin can't open & check LANG_LAST_INDEX_IN_ARRAY

can't open '' was confusing for users so pass the key to open plugin
in theory you could have a plugin that defaulted to these lang_ids
run but its good enough to tell the user what failed to open IMO

lang_id changes mess with open_plugin since it uses them as look-up keys
so add checks for LANG_LAST_INDEX_IN_ARRAY to the checksum

the plugin now removes entries with an invalid checksum

devices with harddrives only append their .dat file so have them skip entries
with invalid checksums and only notify user if a valid entry wasn't found
(these users can run the open_plugins plugin to remove invalid entries)
