Upgraded PI4TUE to fldigi-3.11.1

The server was still running with 3.04, because there is an anomaly in 
which eats 95% CPU on the server. 3.04 took only 5% CPU.

So I was eager to install fldigi-3.11.1. It turned out that also 3.11.1 eats 
95% CPU, resulting in 
problems to decode a PSk250 stream which happens if I try to upload an email 
an attachment.

Next thing I tried was to run 3.11.1 under Xvfb. CPU load dropped to under 5%, 
which means 
that there is a serious problem with how fldigi interfaces with the X-server.

I don't get this problem on the desktop, which has a much faster CPU (the CPU 
of the server is 2 GHz).
It looks like the problem occurs especially when fldigi runs under a vnc 

Anyway, it runs fine now under Xvfb.
To start fldigi under Xvfb do the following in a terminal (use screen as your 
display manager):
Xvfb -ac :99
fldigi -display :99 &

fldigi is now running headless and takes only 5% CPU, leading to a much better
decoding of PSK250
