Add "Providers" functionality, and allow settings weight on them

> Sorry my bad english.

Your English is just fine :)

Nofar from Gizra will check it.

I can confirm this issue. I have OG setup, each group has folders (node bundle) containing a entityreference field to OG audience (og_group_ref). This works fine.
"Within the folder", users can create files (another node bundle), it also has OG audience field (og_group_ref) and an additional entityreference field pointing to the folder it belongs to (field_folder).

Creating a new file is done by a link, e.g. /node/add/file?og_group_ref=12&field_folder=37&destination=node/12. The OG field is prepopulated just fine, however the field_folder throws an error ("Field Folder must be populated via URL.").

It used to work before last update, I just rolled back to 1.3 and it works again. So, version 1.4 is introducing this bug.

I confirm too. I have downgrade to 7.x-1.3. and it works again.

The attached patch will provide additional control when repopulating fields. If the user chooses to use the OG context option, a source priority will be available in the field settings. This will allow to get a value from the URL even if OG context is used.

zihong0, Paul Broon - Could you try it out and see if that solves your issue?

   Make description more clear about what follows what.

   Maybe Use OG-context before/ after URL

@amitaibu-

Added t() function and changed description.

I have taken a different approach, where ER-prepopualte now has "providers" that you can enable and set the order from the UI.

Setting correct version for test bot.

... and correct version.

8: 2162811-er-prepopulate-providers-8.patch queued for re-testing.

Patch fixes test.

Patch adds better backwards computability, and adds tests.

Better title.

Committed.
