option to put spaces between groups when sorting

[naught101]

It would be great to have the option to put a blank line between groups (+projects, @tags), to make them more visually distinct.

I would really appreciate this it would make it much easier to read.
There is a workaround though: simply add a Project tag without a task description (simply: +MyProject ) and it will show up above the tasks when sorting by project (<localleader>s+)
