Use system path and remove package structure in Python components


Currently, the Deemon and Aangel use the Python package structure that save the programs in site-packages folder when they are installed using rpm/msi files created using Distutils.
However, this programs aren't designed to be Python packages, but complete applications, and the package its useless in this case. So a better way to call Deemon and Aangel is by a entry in system path, simplifying the things to user.
