vnc connections don't work

in the latest gnome-rdp release vnc sessions don't work. It depends on a non existant client program and uses wrong parameters to start the vnc process.
This is fixed in 0.3.0.9-2.

IMPACT:
one of three possibilties to use remote desktop is unusable.

FIX:
use xtightvncviewer insted of hardcoded tight-vncviewer and pass the correct parameters to the process

Regression potential:
Low, changed code is isolated from core functionality and unusable in unpatched state.

TESTCASE:
make sure xtightvncviewer is installed
add an identity (ip address or hostname of remote machine) and a vnc profile (any settings) to gnome rdp
create a session for the identity-profile combination.
connect to a pc allowing vnc connections (in system -> preferences -> remote desktop) using the session

You get following backtrace in the log:

Expected: a vnc client opening showing the remote desktop
