add support for patcher preset names in set presets

[x37v]

in the latest develop branch of the runner, there are 2 configuration entries we need to support in the web ui:

{
  "FULL_PATH": "/rnbo/config/set_preset_default_patcher_named",
  "TYPE": "F",
  "VALUE": null,
  "ACCESS": 3,
  "CLIPMODE": "none",
  "DESCRIPTION": "Default set presets store latest preset loaded in instance instead of all of its parameter values"
}

and

{
  "FULL_PATH": "/rnbo/inst/0/config/set_preset_patcher_named",
  "TYPE": "F",
  "VALUE": null,
  "ACCESS": 3,
  "CLIPMODE": "none",
  "DESCRIPTION": "Should set presets saved simply store the name of the last patcher instance preset loaded/saved"
}

re #178

OK I've added support for the former on fde/set_preset_scope_setting. However, I think the description could use some tweaks to make it easier to understand what this actually does. Considering it's a boolean toggle in the UI

Default set presets store latest preset loaded in instance instead of all of its parameter values

seems a bit abstract on first glance. Should it be saying something about "snapshots" vs "presets" or the like?

For the second I am slightly unsure how to deal with it at this point and if it's necessary to address #178. Does this allow to control the same as set_preset_default_patcher_named but on an instance level or what does it add? Reading through #178 and checking the behavior I assume you have already changed the way [/rnbo/inst/<id>/presets/initial works as in being instance, not patcher scoped at this point which I guess gets us there or am I missing something?

Also when visting /rnbo/inst/0/presets/initial it says

"DESCRIPTION": "Indicate a preset, by name, that should be loaded every time this patch is reloaded. Set to an empty string to load the last loaded preset instead"

would it be correct to change this to say "instance" instead of "patch"?
