This was in all stack traces, which confused people ...

We currently only support IE11, so the version check was already old
again ...

When we break old browser versions, we don't check that for other
browsers. So older IE browser just break, like very other older browser
too.

This was needed for IE8 and IE9

Also add "it" as fallback for "oc" and "sc"

The user_email is the first field anyway, and login form as a
user_username field too, so it maybe happens that we already fill in the
user_username filed there before page load finished.

Account migration model/message

added tag for supporting apps prior to Chrome M39

This commit introduces support for AccountMigration federation message
receive. It covers the cases when the new home pod for a user is remote
respective to the recepient pod of the message. It also allows to initiate
migration locally by a podmin from the rails console. This will give the
pods a possibility to understand the account migration event on the
federation level and thus future version which will implement migration
will be backward compatible with the pods starting from this commit.

Add explicit mutual contact creation to the DataGenerator#generic_user_data
which is used in account deletion tests.
