[SailfishDevel] New tutorial for package building

[Jussi Pakkanen]

Hello all

We have added a new development tutorial on sailfishos.org that explains 
how to build and test applications manually. We recommend using the 
Sailfish OS IDE for development but we acknowledge that there are many 
people who wish to use other editors and build systems for their work. 
This tutorial will explain how to do that:

Happy building,
