bugs can specifiy other bugs as dependences

The only thing I miss about blueprints is the abiliy to specify a dependency or co-requisite status on another bug or a blueprint.

It would be uber cool if we could not assign a bug a milestone unless it's pre or co requisite

My head would explode with joy if I could set pre , co and post depenencies via email Something like:

  parent <bug number>
  sibling <bug number>
  child <bug number> <bug number> <bug number>
   done

Use Case:

Lee & Swetha are moving a script to send email reminders from the old code base to the new. A big part of the task is to change paths. It would be cool if their bug was linked to the bug Dan & Mansi are working on to remove hard coded paths from the code.
