web/links/index.htm: updated to Firefox bookmarks: Google Drive: listed bugs that make it very difficult to use (the need to re-download all files when reconnecting a client to an account). added recommendation not to use it (unstable).

removed unused inputs/table.run. inputs/*/table.run include lib/runscripts/table.run directly.

lib/runscripts/datasrc_dir.run: removed postprocess(), which now does the same thing its auto-forwarded equivalent would

lib/runscripts/datasrc_dir.run: removed separate @table_subdirs, because the table-only targets can now safely be invoked on all subdirs, being auto-ignored in subdirs that don't support them

lib/runscripts/util.run: fwd(): enable $auto_ignore so that each subdir doesn't have to have a definition for the forwarded target

lib/runscripts/util.run: added $auto_ignore switch, which causes fallback() not to generate an error that a non-existant target doesn't exist

lib/runscripts/datasrc_dir.run: use new fwd_self alias

lib/runscripts/util.run: added fwd_self alias

lib/runscripts/datasrc_dir.run: enable $auto_fwd, to create the functionality of lib/forwarding.Makefile's `%` target

lib/runscripts/util.run: added $auto_fwd switch
