AE integration in 1.7.4

[repo-alt]

Looks like in OpenComputers-MC1.7.10-1.7.4.1265 AE integration is broke at least with appliedenergistics2-rv3-beta-17.jar
What I did to reproduce:



Mod list:
appliedenergistics2-rv3-beta-17.jar
AsieLib-1.7.10-0.4.8.jar
CodeChickenCore-1.7.10-1.0.7.47-universal.jar
CoFHCore-[1.7.10]3.1.4-329.jar
CoFHLib-[1.7.10]1.2.1-185.jar
Computronics-1.7.10-1.6.5.jar
NotEnoughItems-1.7.10-1.0.5.120-universal.jar
OpenComputers-MC1.7.10-1.7.4.1265-universal.jar

In 1.7.3 it is already broken, 1.7.2 works.
Ae2-rv3-beta-17 is essentially the same as rv3-beta-6 (and the bug reproduces with rv3-beta-6 as well)

I debugged a bit and looks like it was broken in a75992e
when in function li.cil.oc.integration.appengNetworkControl.convert type filter
.collect { case hash: java.util.HashMap[String, AnyRef] => hash }
was replaced with
.collect { case StringAnyRefHash(hash) => hash }

Looks like Scala did some dark magic under the hood when matching HashMap explicitly, and does not do it when matching with case class.
( Registry.convert returns an array of HashMap[AnyRef,AnyRef] )

yep, i broke that in 1.7.10 -- but didn't merge this mistake into 1.12
i see your PR and i'll test it, but it looks good
