Yann E. MORIN 296381ff4f applets/install: don't try to install nothing 
Commit 952d5a6024 (applets/install: accept more than one install
option) changed the way we handle install options: before that commit, a
missing install type would mean to install nothing; after, we would
iterate over options, so we would never notice there was a mising
option.

Fix that by introducing an explicit --none option to specify to install
nothing.
