New string in evolution-data-server

[Matthew Barnes <mbarnes redhat com>]

Added a new password prompt string to the Camel library in
evolution-data-server:

    /* Translators: The first argument is the account type
     * (e.g. "IMAP"), the second is the user name, and the
     * third is the host name. */
    _("Please enter the %s password for %s on host %s.")

This is intended to be THE password prompt string in Camel, and should
replace a number of other password prompt strings having small
inconsistencies.
