Fix strings
Just a few things I caught while translating. I may end up patching this myself but I wouldn’t be mad if someone beat me to it.
- "Save as" should probably be "Save as…"
- "You’ve been invited to join "", you can accept or reject" uses straight double quotes instead of left and right quotation marks (that one may actually be removable as part of #397 (closed))
- "You’ve been invited to join to "… → "to join", not "to join to".
- Time formats should use a ratio symbol
∶
as suggested by the HIG - "Favorites" → "Favourites" (multiple occurrences)
