Added bower and file include info to the installation section

I think this info will make it much easier to start using it... I didn't know that there are different packages for each plugin, what to install, and I also didn't know which files do I need to load, to have those angular modules. I've managed to find everything I needed in various readme files, but this info would make it more simple ;-).
