Proposal: Rename "media" to "data"

[benPesso]

It is a bit misleading to use Media as part of the various data objects' names, as not all shared content is media.

Maybe going with Data or Content will make more sense?

For example:

SharedData sharedData = await shareHandler.getInitialSharedData();

...

shareHandler.sharedDataStream.listen((SharedData data) {
  if (!mounted) return;

  setState(() => this.sharedData = data;
});

@benPesso That is a good point. I'll consider doing this. The main issue is it would be a breaking change, but a simple one for people to fix.

@JoshJuncker You could always add it first and have 2 versions of rollover for devs. Though I think a deprecation notice will be more than sufficient.
