plug-ins: register a separate load handler file-hgt-load for HGT files. 

This allows for it to show as a separate item in the open dialog, with
proper naming. Also add proper arguments so that the handler works as a
PDB function in non-interactive mode, unlike file-raw-load which works
only interactively.
