Since you can't install any other version while the data is present, and it's
hard to clear, it really doesn't help in the ways we hoped.

Just ignore the button press is there isn't one.

We setup the buttons, but never clear them, so when a person has enough
messages in their view and one of them has a button, as they scroll
around and views get recycled the button can be attached onto any
message and not just the ones that actually specify it.

The documentation makes it a bit unclear if the adapter can be set to
null or not... so I just clear it instead. I could leave it, I suppose,
but that feels a bit weird, and the next time we go through this code
we'll just replace it with another one anyway.

Data and Field Element subclasses expect to be able to mutate the list of
children on the original Element that they are derived from using parse.  The
way the new setChildren worked resulted in not actually mutating the original.

Change this for a bindTo that makes sure all fields reference the original (and
hence any mutation on the new object mutates the original) and also a
replaceChildren that uses clear+addAll to ensure that the existing list is
mutated rather than a new list being used.

In practise, this affected room configuration and other data forms being
properly filled out.

When dialling or adding a contact, default to network locale rather than sim
locale.  When syncing contacts prefer sim locale so contacts don't break while
roaming.

Special case the JMP SIM to be from US even though it is actually from FR.

* muc-tags:
  Show and edit tags on MUC bookmarks
  Fix and updates Bookmarks2 support

* next-submit:
  Allow webview to intercept action before sending over XMPP

This path is just for fallback to data stored by upstream, so only use it if
upstream stored their flag.

But only if using bookmarks2, since otherwise any other app is likely to
overwrite and lose them.
