equalize_sidebearings.py: Call RoboFont implementation instead of copy

Comment out the copied RoboFont implementation and call the existing
implementation instead.

We do this by subclassing `SpaceCenterMenuForGlyph` and overriding the
`__init__` method. This allows us to bypass `SpaceCenterMenuForGlyph`'s
`__init__` method (notice that we call its super `__init__` but not its
`__init__`), allowing us to create an instance without needing to
specify the required `event`, `view`, and `callback` parameters that the
original class requires.

This also allows us to not include proprietary code in the project.

Undo functionality _still_ doesn't work. Can't figure out what the
problem is.

This change is really from shortly after the last commit, but I didn't
bother committing because I wanted to resolve the undo problems first.
Since it's been a while, deciding now to commit what's here and continue
working.
