[evolution-data-server] New translatable strings

[Milan Crha <mcrha redhat com>]

        Hello,
just a notice that I committed a change [1], which added two
translatable strings into evolution-data-server, namely:

   Enable _UTF-8 extension, when the server supports it

and

   Unable to connect to POP server %s.\nError enabling UTF-8 mode: "

where the later is used as a GError prefix. The change is for 3.35.91+.

        Bye,
        Milan
