Fix up the nwworkingdir of the help browser's file browser (fixes #237).

Still works in Linux. Also, I can get rid of that ominous gui_dir variable now, which wasn't used anywhere else (wonder what it was good for in the first place, the rest of the help browser code already used pdgui.get_lib_dir() anyway). Stay tuned.

• bd2583de - Get rid of the gui_dir variable which is now obsolete.

Compare with previous version

Ok, everything looking good over here, on both Linux and Mac. Could you please test on Windows, to check that it still works there as well, and merge? (To test, just open the help browser and click the folder button, it should open in .../doc.)

I'll get some sleep and then have a look at the cwd mismatch between GUI and engine on OSX. That shouldn't be too hard to fix either, and then the Mac version should be in good shape.

In the meantime, maybe you could have a look at my other pending merge request !69 (merged) and merge that as well? Thanks.
