Local-axis grab (G key) doesn't work on groups

[j6k4m8]

I think possibly related to #774, "local axis" transforms don't seem to respect groups of objects.

On: Commit 6d669ad

To reproduce, create a square:

Now rotate 45deg and move along local Y,

R45EnterGYY-100

(I'm showing the original location in maroon just for illustration)

Now let's create two squares and group them with ^G, and then rotate the group:

R45EnterGYY-100

Even though the group is rotated 45deg (and the bounding box indicates this), the "local" axis appears to be the same as the global axis. (Actually in this case it appears to be the negative of the global axis, interestingly?)

(PS: I LOVE LOVE LOVE LOVE LOVE GRAPHITE!)

Here's a video showing the problem in action:

It looks like, upon reaching local axis mode, the translation actually ends up going in the reverse direction (but still in global space) which is interesting.

By the way I think this is true of Scale too
