The "current directory" for the process (sbbs.exe, sbbsctrl.exe, etc.) is the
Synchronet CTRL directory and this must not be changed (since all threads share
the current directory).

If you wish to use a relative directory, use "../" or system.mods_dir +
"yourmods" or something similar.

The path should not start with './'.

You need to specify the absolute path or a relative path from "..". There is a
trick where you can 'detect' the directory the script was loaded from using a
JavaScript exception. Here's that trick (invented by Deuce):

var startup_path='.';
try { throw barfitty.barf(barf) } catch(e) { startup_path=e.fileName }
startup_path=startup_path.replace(/[\/\\][^\/\\]*$/,'');
startup_path=backslash(startup_path);
