Add a "Set to Defaults" reset for screen configuration menu option

[GoogleCodeExporter]

What steps will reproduce the problem?

1.  It's not a problem - rather an enhancement request

2.  The /root/.config/Ostinato.conf file stores the Ostinato Window positions - 
but it's not easy to reset if you've messed up the configuration.

I ran into an issue where the entire lower half of the Ostinato screen was 
completely gone (no port stats, counters...etc).  I'm assuming it was an 
in-advertent window resize (maybe I released the button at the wrong time?) - 
resulting in the bottom section being completely gone.  Since there was no 
bottom section visable, I wasn't able to "pull" it back up to a visible size.  
I tried all sorts of screen resizes, but could never get the display back.

I tried to re-install, but it looks like the "ostinato.conf" file doesn't get 
uninstalled when I removed Ostinato - so the re-installed version had the same 
missing screen.

To fix the issue, I discovered the /root/.config/Ostinato.conf file and removed 
it.  Then, when I started Ostinato, it defaulted to a standard display.

If there was a "Set to Defaults" or "Reset Screen" menu option, that would have 
been a handy way to restore the screen display without having to remove the 
file.

It's not a big deal - now that I know about the Ostinato.conf file - but I 
figure it's a fairly simple thing to implement too.

What version and revision of the product are you using (available in the
About dialog)? I had this issue on version 0.3, but it also applied to version 
0.5 (which I upgraded the system to, but corrupted screen position was still 
there.

On what operating system? Opensuse 11.3 64bit
