Initial Set support

[fde31]

closes #182

this looks great, the only thing i think it is missing is the ability to clear the initial set setting.. you can just set it to an empty string via OSC. not sure what the UI should look like for that though

[fde31]

as per the discussion yday - would that operation be a thing if there were to always be a set as in the initial couldn't be empty?

yeah.. there are currently a few behaviors available for startup:

1. load an explicit set indicated by initial
2. load whatever set you last had loaded
3. load nothing

that is all controlled by a config value and this initial setting (or lack there of), i think it makes sense to keep this setup.
