nano: update to 3.0

2018.09.09 - GNU nano 3.0 "Water Flowing Underground" speeds up the
             reading of a file by seventy percent, roughly doubles the
             speed of handling ASCII text, changes the way words at line
             boundaries are deleted, makes <Ctrl+Delete> wipe the next
             word and <Ctrl+Shift+Delete> the preceding word, binds M-Q
             to 'findprevious' by default (the Tabs-to-Spaces toggle is
             placed on M-O, and the More-Space toggle is fully removed),
             makes an external spell check undoable, shows the correct
             number of lines on the status bar when opening multiple
             files, removes the 'formatter' command, removes the
             'searchagain' bindable function (M-W is now bound to
             'findnext' by default), moves the No-Convert toggle to the
             Insert menu, removes the Backup and New-Buffer toggles from
             the main menu (they remain in the Write-Out and Insert
             menus, respectively), is more precise in what it accepts as
             a rebindable key name, ignores any presses of <Esc> before
             a valid command keystroke, recognizes some more escape
             sequences for modified editing-pad keys, does not hide
             rcfile error messages on a Linux console, renames the
             bindable functions 'copytext' to 'copy' and 'uncut' to
             'paste', and avoids a possible hang during a Full-Justify.
