Makes Machine Overridden machines no longer attack borgs

Adds a 'silicon' faction, all AIs, borgs and machine overridden machines
are in this faction.
Also adds some feedback text to malf powers, gives span classes to some
already existing feedback messages.

Fixes a few typos and errors in descriptions.

/red is not welcome, removed.

Just to be clear: overriden machines don't attack ANY borgs or AIs.
