Only set '&ut' when allowed and it is unchanged yet

Set '&ut' too low might break many things, it is up to the user.

If multiple files are given in the auguments list and the last one has
not been edited yet, issuing ':q!' suppose to quit anyway, but it would
fail if '&ut' is too low (e.g. 300ms).

Improve quiting if MBE is the last open window

If the last file of argulist has not been edited yet, executing `:q`
command would fail. Executing ':q' twice or ':q!' should quit anyway.
Since MBE is the last open window, we need to some how behave the same.
Quiting when executing ':q' twice has been implemented, but quiting when
executing ':q!' is hard to implement, because how can we know the command
that triggered this autocmd is ':q!'?

Only need to reset the '0 mark if MBE is the last window

If quiting vim fails due to some reason, we reset the '0 mark to the
last file, and abort all the other operations, this would let vim hanle
the rest.

The nesting of autocmds must been enabled on quit command to let other
plugin window be able to fire necessary operation.
