Issue list and draft JLS/JVMS text updated

[mark.reinhold at oracle.com]

FYI, I've updated the issue list to link to the latest proposals for
#ReflectiveAccessToNonExportedTypes and #AwkwardStrongEncapsulation,
to link to the first proposal for #NonHierarchicalLayers, and to
include the new issue #IndirectQualifiedReflectiveAccess.  (I added
#DiscardableModules and #ReadabilityAddedByLayerCreator last week.)

I've also updated the draft JLS/JVMS text to include changes for the
open-modules/packages proposal:
