tortoisehg freebsd port update

[Joan Picanyol i Puig]

[followup, adding PyQT people]

tl;dr: tortoisehg does not work on FreeBSD 11.2 + 2018Q4 ports branch because
    of version mismatch

Unsure whether this is an option to get tortoisehg going unless Qt5 is also
upgraded, or a local patch is kept until then, see below.

Well, that didn't work out too well. Downloading tortoisehg-4.7.1 or 4.7.2 and
trying to run it with python2.7 fails saying:

   #!python

        action.setShortcutVisibleInContextMenu(True)
    AttributeError: 'QAction' object has no attribute 'setShortcutVisibleInContextMenu'

However, this method was introduced in Qt 5.10
http://doc.qt.io/qt-5/qaction.html#shortcutVisibleInContextMenu-prop and we
only have Qt 5.9 in ports.

At this point I suggest we update tortoisehg to 4.7.2 with a patch until kde@
upgrades Qt. I've reverted
https://bitbucket.org/tortoisehg/thg/commits/244ff3f444682ee41c934e0c0c977b67f19f835d
locally and can successfully start tortoisehg-4.7.2 with it.

keep up the good work
