OSX: fix paranthesis in last commit

OSX: add a fix for lion_fs loosing handles after calling fs from key shortcut, also reenabled lion_fs for OSX >= 10.9 again

Maybe slightly controversial pie commit:

Make pie menu item placement touch the radius from the internal side of
the buttons rather than placing on the center on the cirtcle. This
allows us to get rid of the separate visual angle property, also allows
for tighter placement of pies with a smaller radius without easily
overlapping.

Also pie menu title now always appears above the threshold indicator.

Add custom property to previous commit, name "Context" of that property
was misleading.

Correct missing new line in the debug print

Align pie menu title on center.

Bring back python operator for pies on a certain operator property.

Image Editor: only do alpha test if output file requires alpha

(internal change, nothing should change to the user)

Fix T41219: Cycles backface detection doesn't work properly

Root of the issue goes back to the on-fly normals commit and the
latest fix for it wasn't actually correct. I've mixed two fixes
in there.

So the idea here goes back to storing negative scaled object flag
and flip runtime-calculated normal if this flag is set, which is
pretty much the same as the original fix for the issue from me.

The issue with motion blur wasn't caused by the rumtime normals
patch and it had issues before, because it already did runtime
normals calculation. Now made it so motion triangles takes the
negative scale flag into account.

This actually makes code more clean imo and avoids rather confusing
flipping code in mesh.cpp.

Correct menu items active behavior applying to dialogs

Fix T40717: Screen does not update while scrolling or zooming with touchpad on a laptop

This is rather workaround solution for now, which seems to
work and it's not that huge to maintain (one liner apart from
the comment).

Idea is to make sure PeekMessage peeks the message when window
proc receives WM_MOUSEWHEEL (some touchpad drivers seems to
swallow the messages making it so PeekMessage doesn't get
anything).
