Dumps and init files from before 0.0.4 load no more of their old tag formats, and three orphan test scripts go

A2: a restored pane's tag tail comes from the dump's tag_tail, which every dump since 0.0.4 writes; the 27 earlier default tails that were recognised to upgrade, restoreTail, tailClass, savedPrefix and restoreTailAt, pdf_view's and image's legacySavedPrefix, a terminal's TTY tag prefix and its raw output tail replay, and the ThemeSel, FontSel and ColumnTags words (init lines and dumped output names) go, with their tests; the CHANGELOG says so. A4: test/fs_soak.py, referenced nowhere (monkey9p.py does its work). A6: test/column_grip.py and test/look_placement.py, referenced nowhere; the six review scripts docs/ui-review.md names stay.
