#10 Separation of utils from the underlying library

[Adam Radziszewski]

The buildprocess of previous Poliqarp versions triggered a build of binaries, which rendered it very hard to integrate Poliqarp into other applications (the only viable way was to make a fork). It would be much more convenient and flexible to have the core functionality stored in shared libraries with well-defined simple API. The command-line utilities could be then very simple pieces of code that just use the library (or libraries). The same could go for the GUI.
