Title: Possible bug when setting a BOOLEAN attribute to false

Using the "object.attribute=false" setter always saved the attribute as TRUE.
This was because the code was checking for the value in the following way

```ruby
if value
@values[ attrtype.name.to_sym ] = value
else
@values.delete( attrtype.name.to_sym )
end
```

Also i made a really lazy modification on Treequel::Directory. I did not want to dig any further because i want to confirm the bug first.
