Fixed chunkinfo and RAllocatorHelper crashes. Details: * Tidied leak docs * Updated dialog command to workaround text windowserver bug and implement DIALOG_IMPL as an enum option. Also tried to support dismissing the dialog with CTRL-C but ended up just printing a warning as the notifier API is broken * Fixed RAllocatorHelper::OpenChunkHeap() (and thus chunkinfo <address>) and took Adrian's latest changes. * Fixed chunkinfo OOM problem
