End DCS/OSC strings at any ESC, default the external terminal to Terminal.app

A string with no ST swallowed every later sequence, RIS included, and
Clear Screen could not recover the tab. Any ESC now ends it, as in xterm,
and the sequence it starts is dispatched. The shipped setting needed Kitty.

Also: REP, SCOSC/SCORC, DECOM-relative CPR, `:` subparams and more DECRQM
modes answered; new rows inserted in one edit; controls stripped from
pastes; wide-char mouse columns.
