Made project selection more easy, updated puppet code to select which modules to include (now based on a facter variable)

Added a simple way to switch between different set of build dependencies using a custom facter fact.

Added basic readme, renamed build folder and added it (and it's relevant subfolders) to version control

Switched from sharing the whole rpmbuild folder to only share the specs, sources, rpms and srpms subfolder, because there is an error with symlinks and shared folders
