Minor LinguaPlone changes

Hi:

I have a couple of changes to merge into LinguaPlone trunk, but I
wanted to comment them here, in case someone has any objection:

1. Show the language list in "translate into" menu in its native form:
Currently the menu shows the language names with its english name what
is many times weird for users. Moreover the language change viewlet
already shows the language name in its native form.

2. Mark current content's translations for search engines: Google
published in december a way to mark the translations of the current
content with HTML <link> tags. This change adds a viewlet in the
header section with this URLs. More information about Google's
suggestions:

These changes are in my current fork of LinguaPlone in GitHub, if
there's no objection I merge them into the trunk (or master or
whatever... I am not yet used to the github workflow... ;))


Best,


Mikel
