Mirror broken beam direction

In some cases, I think particularly with irregular or composed time signatures, a broken beam might point in either direction or the 'wrong' direction might be preferred by the composer, to indicate specific rhythm(s).

A way should be given to flip the broken beam direction automatically chosen by the program.

(As a side note, this could be helpful to fix the -- hopefully few -- corner cases in which the automatic program choice is wrong).

From the UI point of view: a shotcut already exists to mirror the note heads, it could be used to mirror broken beams too; a direction selector could be added to the beam Inspector.

Thanks,

M.
