Repeated error message on tasks with multiple parents

[Bryce Harrington]

I upgraded my tasks to the 0.3 branch today. After installing it, on starting it up it prints a slew of warnings:

Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.

It would probably be sufficient to print it out a few times and then just indicate that the warning repeats. E.g. something like:

Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
Warning : get_parent will return one random parent because there are multiple parents.
[Last warning repeats 42 times...]

There's also a large amount of whitespace between 'because' and 'there' which could be cleaned up better.

This message is there to see what are the problems with multiple parents. So far, I didn't see any. The full message should be removed before 0.3 release (and bugs should be fixed, of course)

This at least makes the message only print out a little, so that error messages don't end up scrolling out of your buffer.
