Alt key broken in VNC server 

Hello,

When using Debian testing with your wonderful LinuxDeploy tool for Android, I noticed that the Alt key is broken in the VNC server.  [The solution](http://www.realvnc.com/pipermail/vnc-list/2002-January/027719.html) is to pass the `-compatiblekbd` option to the `Xtightvnc` command in the `/data/local/bin/linuxdeploy` script.

Thanks for your consideration.
