Add Annotated Memory Viewer feature to SA's HSDB

HSDB has a Memory Viewer feature that brings up a window that shows the memory contents in a specific address range. It basically looks just like the clhsdb "mem" output. The recently revived "mem" command (see JDK-8244669) adds a -v options which causes PointerFinder (aka findpc) to be called on each value in memory to provide details about what the value points to (if it is an address). It would be nice if HSDB also had this feature. I propose adding a new Annotated Memory Viewer feature to do this. See the attached image that shows the current Memory Viewer window, and just below it the proposed Annotated Memory Viewer window showing the same address range.
