Test Xinerama support on multi monitor setup

[GoogleCodeExporter]

In the latest development version support for Xineram was introduced.
To turn it on add '--xinerama' argument when running pywo from commandline, or 
add 'xinerama = on' in the '[SETTINGS]' section of the configuration file.

Since I don't have access to multi monitor setup this feature still needs some 
testing.

I don't know if current implementation works with all window managers, if the 
screen area is calculated correctly for different panel/docks placement.

If you are using pywo with more than one monitor screen please check the new 
xinerama support and in case of any problems please paste (or link to) output 
of 'pywo debug' command.

Seems to ignore the top GNOME panel when tiling on the 1024x600 screen in my 
setup. The bottom panel is taken into account correctly.

Is it always visible, or autohiding is on?

There's something wrong with this:
<Strut left=(0L, 0L, 0L), right=(0L, 0L, 0L), top=(0L, 256L, 1279L), 
bottom=(0L, 0L, 0L)>]
The window manager reports that top panel has starts at x=256, ends at x2=1279 
(that's the smaller screen, ok so fat), but the reported height is 0, which 
causes the problems. 
Just checked and it seems that panel (gnome panel) with autohide is reported to 
have height = 1, so that's not the case...

I posted a separate issue about my problem using two differently-sized 
monitors. (My gnome-panel equivalent (mate-panel) is in the horizontal monitor, 
and pywo cuts off the vertical monitor's layout space as if the gnome-panel 
extended all the way across both monitors). Here's the output from my debug 
command:
