Memory leaks in intersection-observer-admin

[XuluWarrior]

I was just watching a talk on EmberFest and learned that intersection-observer-admin 0.3.2 has memory leaks (snewcomer/intersection-observer-admin#49, #54, #55, #56 and #58)

These have been addressed in 0.3.4.

Is there any intention to update this package to minimum version requirements?
