Pjb dev 3 (#48)

* Undo array allocation changes from #43

Doesn't work

* Expand dmeter heap sizes, give names

* Fix manual operator delete call in resource.cpp

* Disable map rendering for now

Aurora can't handle lines

* Re-enable assert heap on DVD thread

Should be fine?

* Some basic debug groups with the new Aurora API

* Allow Aurora backend to be set via CLI

* Give materials debug groups

* More debug groups

* JKRHeap separation: array edition

Pain
