Title: Cleanup view properties - stabilize view memory usage

Ensures views clean up properly when being destroyed. Properties were not being killed, resulting in change event listener leaks. This should go a long way to flattening the memory profile when loading many views or navigating in an app.

Also removes memoized functions causing excessive closures, extra memory and references at GC time
