osc.lua add idlelogo and osc-idlelogo

This is mainly for other user scripts that may conflict with the osc
logo in some way. Although it is possible to listen for
shared-script-properties, this has many edge cases that could easily pop
up. A user could want other OSC things to happen at the same time (say
osc-message). They just don't want the logo. The idlelogo option
disables all logo related things (including the santa hat) if it is set
to "no". A new script message (osc-idlelogo) is also added so users and
scripts can easily toggle the value (passing "cycle" or just explictly
setting "yes" or "no"). Some more discussion on this is found on the
below github issues.
