general: make five tools accessible through the "Execute Command" menu

Instead of creating a special Tools menu, add the five functions that
affect the whole buffer to the "Execute Command" menu.  There is room
for these five functions there, and they kind of fit in because three
of them (Speller, Linter, and Formatter) actually invoke an external
command, and Full Justify could have been implemented externally, and
the destructive Cut Till End ought to have required a double keystroke
since the beginning.
