[Develop] added a needsinfo resolution in bugzilla

[will]

I had in my todo list a task to add a NEEDSINFO resolution to Bugzilla. 
  I added it just now.

We can change it if it doesn't work out.  I don't recall offhand what 
the circumstances were that resulted me in adding it to my todo list.

So the use case for the NEEDSINFO resolution is this:

"""
User Bob creates a bug related to some problem he's having.  Developer 
Susan looks at the problem, but needs more information from Bob--say she 
needs a screenshot because the issue is ui-related.  Susan adds a 
comment to the bug along the lines of "Bob--can you attach a screenshot 
so that I can see what you're seeing?" and switches the resolution to 
NEEDSINFO.
"""

This makes it much easier for us to query all the bugs that are in a 
NEEDSINFO state and push them along.  Bugs that haven't gotten new 
information after some time can get a friendly ping.  Bugs that haven't 
gotten new information after some time and a friendly ping can be moved 
to INVALID or WORKSFORME or something like that.

This will help us keep bugs moving along and will reduce the number of 
zombie bugs that we've got sitting around ad infinitum.

Any thoughts, suggestions, concerns, etc...  reply here.
