Enable SSH before first boot on Raspbian

I leave you a quick tip about *Raspbian* I read in the official forum:

It is possible to activate the *SSH* daemon creating an empty file in */boot* called **ssh** after burning the operating system. Now when you start your distro for the first time, *SSH* will be activated and the file will be deleted automatically.
