Introduced a minimal version of RetroShare.

You can enable it in libretroshare.pro and RetroShare.pro by uncomment
CONFIG += minimal

This enables two new defines for stripping all not needed things
- libretroshare: MINIMAL_LIBRS
- GUI:           MINIMAL_RSGUI

and removes not needed files from build (see end of the files libretroshare.pro and RetroShare.pro).

Beware: All data of the stripped services are lost
