Font sizing differences

[Volkor3-16]

Since I've installed mumble on linux, I've been noticing that the font has been a little larger than the windows build. I've added a comparison between the different builds here:

(changing DPI just makes the font smaller, leaving the spacing the same)

Now, at that current user level it doesn't seem much like an issue, but when the server fills up, there is quite a large difference in the size, which eventually causes a really long scrollbar for just a few extra users.

I've talked on the irc about this, and it's apparently because of the different fonts used compared to windows, and there was talk in the past to use a standard font.
