Two string changes for Nautilus

[Cosimo Cecchi <cosimoc gnome org>]

Hi again,

I would like to ask a string freeze break request for two strings in Nautilus:
- https://bugzilla.gnome.org/show_bug.cgi?id=680983 - this is about
changing the "Send To..." string of the nautilus-sendto extension to
"Email...". nautilus-sendto used to offer a set of options other than
email, which are currently not really working correctly. In the bug
there's a patch to change the extension to open the email client
directly instead, and this should be mirrored in the string displayed
in the UI.
- https://bugzilla.gnome.org/show_bug.cgi?id=683752 - when an user
tries to open a file for which there are no applications available, we
show a message saying "There is no application installed for %s
files". The patch adds quotes around the %s, to ensure the file type
stands out from the rest of the string.

Thanks,
Cosimo
