#73 Add option to change ellipsis mode for tab titles

[Scott]

Whenever the title gets long enough that it starts to ellipsis, it basically gives me no information.
I've confirmed and built a change locally to turn this off, all you have to do is change src/multitab-label.c:247 from "PANGO_ELLIPSIZE_MIDDLE" to "PANGO_ELLIPSIZE_NONE", "PANGO_ELLIPSIZE_START" or "PANGO_ELLIPSIZE_END" at the line:
gtk_label_set_ellipsize (self->label, PANGO_ELLIPSIZE_MIDDLE);

I realize there's a possible tradeoff here. Having no ellipsis means that there's more tab scrolling required. Personally I found "MIDDLE" to be the least useful, and have settled on using "END", as when I'm on my local machine the ending folder(s) are the most important in distinguishing where I am, and when I'm on a remote machine, the ending of the machine name is the most important.

I think having this be an option in the tab setup screen would be nice.
