Add command to squash all fixups in the current branch

To do that, change the "Apply fixup commits" command to show a menu with the two
choices "in current branch" and "above the selected commit"; we make "in current
branch" the default, as it's the more useful one most of the time, even though
it is a breaking change for those who are used to "shift-S enter" meaning
"squash above selected".
