If there was a todo with 'foo:somestring', it wouldn't be returned with
the command above, because somestring couldn't be converted to a date or
an integer, and therefore the OrdinalTagFilter just returns False.

As a final fallback, use a GrepFilter match to do the string comparison
such that the todo item(s) with this key:value combination will be
returned.

Priority Aa or AB is (still) not allowed.

The previous commit had the archive condition on the wrong place,
resulting that todo.txt files were not written out at all if archiving
was disabled.

Also introduce the (overall) -a flag to disable auto archiving. -a comes
from the original todo.txt CLI.

It would have been nicer to have DoCommand support the -a flag, however,
DoCommand doesn't know anything about archiving and I would like to keep
it that way.

Addresses issue #42.

(Note that commenting/omitting archive_filename will still by default
write the archived entries to done.txt).

This addresses issue #42.

Expression-mode for del, depri, do, pri, postpone.

Fell into the trap of calling a function as a default parameter. Because
of this, relative dates used with the 'add' or 'do' command (recurrence)
were based on an offset when topydo was started, not when the subcommand
was executed. Usually these two events occur in the same second and this
bug was unnoticed for a long time. But now with prompt mode, this bug
may surface if you leave running topydo for longer than a day.

- add test for direct todo.txt editing
- remove unneceseary `u()`

- execute_multi_specific() -> _execute_multi_specific()
- execute_not_multi() -> _execute_not_multi()

MultiCommand._catch_todo_errors() prevents occuring of those.
