 This patch fixes following issues:

 1. At login time status is set to ''available'' with no msg afterwards set
 to desired status, which leads to users that connects as ''invisible'' to
 appear ''available'' for short period of time

 2. Status message's `purple_markup_strip_html` should happen before
 encoding conversion as it is UTF8, unless we want some junky ?? characters
 in status message in place of non-ASCIIs

 3. Additionally: "Load buddylist from file..." wasn't marked for
 translation

 This patch adds `ggp_to_gg_status` which converts `PurpleStatus` into
 Gadu-Gadu status + msg, this helper is used in `ggp_set_status` and
 `ggp_login` to fetch desired status.

 Tested with latest ''Adium''.
