Consider making the chat announcement something like

Summon: <name> ( Priority: <p> / Total Summons: <n> )

The current version uses the Blizz-translated SUMMON but this would require the whole string be translated with placeholders, so it better be perfect first.

For readability it would probably be better to abbreviate some of it but that is just way too hard to translate.

This is split off #96

I think the text should probably be:

Summon: <name> (Priority: <p> Count: <n>)

Maybe there is a better word than "count" for "total number of summons"?
