Patch to get the Option Key working on OSX connections

[gjpc]

While not being a registered developer, I have patched the current Source Forge tarball so I am cross posting my patch here.

I have a patch that enables uVNC to send the option key to OSX machines using the native OSX connection.

It is simple: in file keysymdefjap.h line 1506 change XK_Super_L from 0xFFEB to 0xFFE8

The tarball did not compile out of the box. I had to remove line 5 #include <d3dx9.h> from directxviewer.h
I had to add the ./omnithread directory to the vncviewer includes directories
I also manually moved the omnithread.lib into the vncviewer build directory, I am prefer Eclipse so I do not want to figure out the vagaries of VStudio.
Once I added nasm to my cygwin the viewer did build.

I do not use uVNC to connect to Win machines so I don't not know if this change is a burden for win to win users.
If they need the key, then a check box in the configuration would be appropriate to switch between the two values in the ClientConnection.cpp ID_VK_LWINDOWN & ID_VK_LWINUP message handlers around line 6723.

Due to the very low activity in the developer forum, especially about patching I am reluctant to go any further with my patch then what I have.

Enjoy
