Make github a multisource widget

[Seanstoppable]

Note, that this is a backwards incompatible change

Previous config:

repositories:
  wtf: "wtfutil"

New Config:

repositories:
- "wtfutil/wtf"

It doesn't have to be backwards incompatible. There's already an established precedent for changing config types. See how opsgenie handles schedule.

In this case you'd first try to cast to UList. If that works then no change necessary. If that raises an error, then try to cast to UMap. If that doesn't raise an error, concat all the map's values and keys together (ie: "wtf": "wtfutil" becomes "wtfutil/wtf") and create the list of those.

Thanks! Will take a look

There is one major difference here in that MultiSourceWidget expects a specific config type to get the sources.
However, like how scrollable items were being handled, it was really only trying to use them to get the length, and I can refactor multisourcewidget to update that length vs reading config

[senorprogrammer]

I'm not sure what you mean. It looks like Multisource reads the len() of its Sources attribute, which is []string. That can still be built that way during the settings loading. Or am I missing something?

[Seanstoppable]

You are correct, I am now handling both configs and works fine by setting Sources manually in construction.

Thanks!
