synergy.conf.example: clarify comments

instead of saying apparently absolute statements
like "Foo is to the right of Bar",
use relative phrasing "for Bar, Foo is to the right".
This makes it clearer that the configuration file
does not describe a globally consistent spatial arrangement
but rather a set of areas that can be linked in arbitrary ways.
