Changed readme twice, see description

[jonathan-kuhn]

I have made two changes to the readme:

1. changed the list of supported devices because I have tested it on Apex 7 and it works
2. changed the install command for installing the dependencies on Ubuntu, i removed dbus-dev and replaced it with libdbus-1-dev

dbus-dev is not found by apt on installation and when building with the command in issue #60, I get an error message telling me I have to install libdbus-1-dev. After installing libdbus-1-dev it builds fine for me.

And a very quick idea: maybe the command given in issue #60 should be added to the readme until linkme gets fixed.
