Tab key FIXED in applet viewer

[vnclist@rgm.nu]

Tested on both MS JVM (Java 1.1) and Sun 1.4 JVM on Windows 2000 and 
Windows XP, using IE6 and Firefox 1.0 (all combinations).
This fixes the issue I mentioned in:
    http://www.realvnc.com/pipermail/vnc-list/2004-August/046419.html
Also described at:
    http://www.realvnc.com/pipermail/vnc-list/2004-March/044470.html

Using the RealVNC 4.0 java applet, the tab key was not functioning.
This patch fixes that problem.  For compatability with MS JVM, remember 
to use javac -target 1.1 when compiling the jar file with Sun's compiler.

Here's the diff:

    // initGraphics() is needed because for some reason you can't call

I hope something like this gets included in the official VNC distribution.
