[texworks] SCRIPTING: 1. __FILE__ not quite true and 2. TW.system not handling - or _ in path structure(?)

Hm, this is weird. __FILE__ is provided directly by the QtScript API,
though, AFAIK. Tw doesn't do anything with it (nor does it exist in,
e.g., lua). So this might be a Qt bug (but then again, I'm not sure if
this feature is documented at all - probably that should be checked first).

This is strange, too. Again, Tw doesn't do anything with the command
line, it passes is straight to
http://doc.trolltech.com/4.7/qprocess.html#start-2. So, two suggestons:
 * Does it work (for a path without spaces) if you remove the quotes?
 * Does it work if you escape the quotes
(http://doc.trolltech.com/4.7/qprocess.html#start-2 actually has an
example on `dir`).
