The JavaScript function

mjsonrpc_db_save / mjonrpc_db_load

have been dropped from the API because they were not considered safe. Users 
should use now the new function

file_save_ascii()

and

file_load_ascii()

These function have the additional advantage that the file is not loaded 
directly into the ODB but goes into the JavaScript code in the browser, which 
can check or modify it before sending it to the ODB via mjsonrpc_db_paste(). 

Access of these functions is limited to <experiment>/userfiles/* where 
<experiment> is the normal MIDAS experiment directory defined by "exptab" or 
"MIDAS_DIR". This ensures that there is no access to e.g. system-level files. If 
you need to access a directory not under "userfile", us symbolic links.

These files can be combined with file_picker(), which lets you select files on 
the server interactively.
