output: implement CAGE_MULTI_OUTPUT_MODE_LAST

Browse source 
In this mode, only the last connected output will be used. If that one
is unplugged, the previously last connected output will be enabled. This
for example allows one to switch between two outputs, e.g. on a handheld
device such as a mobile phone.
