VDR-Manager

Please check the line ~218 in sock.cpp

I've added zlib compression, on 1400 channels it gives factor 4 in the size. But I'm not sure How to add this properly the current state.
Proofce of concept works, but if I use -P option and so I give password from android, !OK comes correct but then the result of a command is -1 in androids is.read();

Also we need may be
1) specify command line option to enable compression or android also must become this in preferences.
2) Automatically switch to compression, then we need some compat modus if a old client comes.

Done
