On MacOS raising a window causes the focus to be transferred
to it -- although it may actually be a bug in the Tcl/Tk port.
When this happens with the blame viewer tooltips, it makes
the interface less usable, because Entry and Leave handlers
on the text view cause the tip to disappear once the mouse
is moved even 1 pixel.
This commit makes the code raise the main window on MacOS
when Tk 8.5 is used. This version seems to properly support
wm transient by making the tip stay on top of the master,
so reraising the master does not cause it to disappear. Thus
the only remaining sign of problems is slight UI flicker
when focus is momentarily transferred to the tip and back.

An ugly hack, but it makes at least my experience better.
Unfortunately, even it requires manually installing Tk 8.5.
I wonder if there is a better fix.
(maybe, tweaking Enter and Leave instead?)
