Removing APSB13-03, not ready.

This was landed by @todb-r7 on #1709 but that was premature. #1717 was
a proposed set of fixes, but it didn't go far enough.

@jhart-r7 and @jvazquez-r7 should revisit this module for sure, there's
some good stuff in there, but it's not ready for a real release quite
yet. Take a look at the issues discussed in those PRs and open a new PR
with a new module?

Sorry for the switcheroo, not trying to be a jerk.

[Closes #1717]
