Get the linux redistributable of the Data Explorer finally working ...

With this all needed shared libraries (except system libraries) get packaged for Linux. I tried creating the package on dev2 (Centos) and was able to run the binary on a Ubuntu 12.04. virtual machine. Although the Data Explorer has to be started by a shell script which modifies the `LD_LIBRARY_PATH` (but only for the Data Explorer executable).

This fixes #33.

I merge this by myself to test it on Jenkins.
