vi: Add tests

Test file integrity after load, move, delete and save+exit. Drawing
of buffer is not tested yet.

Added -s script option, accept file that is run as startup script of
commands. File is parsed byte at time and handled as you had typed it.
If EOF has been reached without editor close command, editing is
continued normally using keyboard. This functionality is in vim and
neovim, but not in POSIX vi standard. nvi (vi used in some macs) has
-s with different meaning...

Some simple tests added, dw last line test fails, so test is disabled.
