#1 Clicking any "..." button should open current dir

[Chris Thomas]

When you click the "..." button in the options window,
it should use the current directory or / if no
directory is entered instead of defaulting to the home
directory as it seems to do in my case.

if you have entered

/mnt/drivec/Data/lightwave/content/

and you want to change it, you dont want to open a file
selection dialog starting in the /home/usr directory
(in my example) in most cases I've wanted to start in
the content directory I had selected already and modify
it to a nearby directory which would mean the interface
is quicker to use.
