Outline staus text of tooltip
problem
Color of status of tooltip is arbitrary.
analysis
Because color of status is arbitrary, not all colors of all statuses of Gajim fit well with a color scheme every theme.
enhancement recommendation
Outline text of status so that it would be better readable with most, if not with all themes.
\<p style="color: yellow">Away\</p> vs. \<p style="color: grey">Offline\</p> (I do not know how to outline HTML fonts without using CSS)
