Remove Default Segments

[#1]

It would be great if we were able to hide or remove default segments.  For example, the segments "Purchasers" and "Non-Purchasers" do not apply to Financial Services or lead gen clients.

[#2]

it would also be great to be able to change the devault segments to match our rules - for example generic paid search definition doesn't align with our rules - but no way to fix or change

[#3]

This was implemented in our Spring 2014 release.
