Added nintendo switch support (#16)

Browse Source 
This PR adds support for building sm on the nintendo switch, the
installation instructions are pretty much the same, with the difference
that you need a switch with atmosphere installed and the devkitpro
development environment, to install on the switch just copy the .ini,
the nro and the smc file.
