[#1409] Fix the e-mail bodies' translation strings

We ended up creating a string with extra whitespace before the paragraphs,
like "...to be reset\n\n Please click the following...".

But the i18n message key doesn't have these whitespaces, so we always send
that in English. To solve it, we could either fix the message key in all .po
files, or change how we construct the string in mailer.py. I prefer the
latter.

[#1409] Change string formatting to use "{foo}".format(foo="bar")
[#1429] Pass came_from to login handler after creating a user

Otherwise you lose the language setting for the UI. I'm not entirely
sure but that may involve two redirects.

Merge branch '1420-group-view-schema-fix'
[#1446] Enable DataPusher for private datasets

There's no need to prevent the import to the datastore on them, as the
datastore will manage the authorization, and logged in users still
expect these files to get imported to the DataStore.
