Title for missing migrants infobox

[erictapen]

I think we should provide a bit more context to the Missing Migrants infobox. Currently the title is just "Missing Migrant", which doesn't really provide the user with much information on why we included this curiously mis-aligned infobox on top of everything else.

Maybe we could change the title to something along the lines of "Not all people on the move can be accounted here. Read here about migrants that go missing" etc.?

Stimmt, die Begründung fehlt etwas. Gute Idee

Vielleich so? "Not all migrants who try to make their way to or through Europe arrive safely. That is why some never get to apply for asylum in the first place and therefore cannot be accounted for here." Und dann den Untertext?

Klingt top! Weißt du wo du es einfügen kannst? Vermutlich reicht es in src/Main.elm nach "Missing Migrants" zu suchen.
