Dear Developers,

In orca.desktop.in file not present the --replace parameter with exec line.
Original exec line is following:
Exec=orca
The right line is following, because Orca now have a --replace parameter, with replaces the current running Orca process if present:
Exec=orca --replace
If this change is not present and have an already running Orca process, if the user click the Orca desktop icon for example the Applications/accessibility/Orca Screen Reader And Magnifier icon, Orca is launching, but two Orca process is running, a prewious existing Orca process and the new started Orca process.
For example, this is result two spokened speech output, for example:
Quit Button.
Altq
To activate, press space.

Quit Button.
AltQ
To activate, press space.
This is very disturb.

I maked a simple fix patch, with absolute sure solving this problem.
I tested my patch with Orca already running, Orca is launched correct and replace the existing process. If Orca is not running and clicking the desktop icon, Orca is launch correct, so, this change not producing any problem.
